Homeostasis Essays (Examples)

Homeostasis can be maintained as long as there are no long-term changes in the physiological factors that directly influence it. A settling point is established when there is a balance between opposing forces. These points are capable of change and are likely to do so when the opposing forces alter their balance (Berridge, 2004).

The drive reduction theory also addresses the motivational drives to maintain homeostatic regulation. In this theory, a stressor that takes the form of a homeostatic emotion disrupts the internal balance and provokes a drive state in which a motivational drive to restore balance becomes priority (LaGraize et al., 2004). The drive is the internal tension that develops that motivates the organism to act in order to reduce the state of tension. In the case of hunger, hunger induces the motivational drive to locate and consume food in order to stop the feelings of hunger, replenish nutrients…

The central nervous system is responsible for interpreting the signals sent by these organs, which are meant to reflect energy stores, the recent nutritional status of a person and other factors related to energy metabolism. Further the authors point out that parts of the central nervous system including sections of the hypothalamus then coordinate energy intake and expenditure. The authors suggest that manipulation of any of these components may be an avenue for obesity research. Like the previous researchers discussed, the authors suggest that the homeostasis of the body can be manipulated both intentionally and un-intentionally by individual's lifestyle and personal behaviors.

In fact all organs of the body work synergistically to promote homeostasis. As Westerterp, Plasqui & Goris (2005) note water is vital to energy homeostasis and is directly impacted by factors including physical activity and water loss due to temperature. The authors conducted a study of forty-two women…

Homeostasis may be defined as a self-regulating process whereby equilibrium is achieved between various organs or segments of an organic system, such as the human body. The term "homeostasis" was first coined in 1932 by American physiologist Walter Cannon (Freeman, n.d.), who observed that organisms have mechanisms in place to maintain a constant state of equilibrium or balance. The term has subsequently been utilized to describe this process of maintaining equilibrium in many different situations.

Homeostasis has also been formally defined by many scientists in different ways, perhaps most accurately as the "maintenance of a stable internal environment" whether in a cell or in the organism as a whole (MSNucleus, 2004). Homeostasis is in essence equivalent to a state of equilibrium. Much like balanced scales, homeostasis ensures that too much nor too little exists at any point in time within organisms. When a state of imbalance occurs, the scale tips…

Homeostasis: Sleep and Health

Sleep and Health

How Sleep Homeostasis Helps to Maintain Human Health

This booklet is designed to answer questions about how the human body's cycle of sleep and wakefulness, and to explain a few ways that sleep contributes to overall health.

The Sleep System

Sleep is governed by internal changes in the body that work together to produce healthy patterns of sleep. Over the course of our waking hours, our homeostatic sleep drive strengthens. The level of brain activity is associated with our patterns of sleep and wakefulness. Sleep theory suggests that adenosine is produced when active and alert brain cells use energy. Sleep drive and adenosine increase in concert during wakefulness, and the level of adenosine in the brain dissipates as the sleep drive lessens and we enter a stage of wakefulness. How deeply we sleep or the length of time that we sleep varies according…

A seed is really a small plant embryo, surrounded by a nutritional layer known as the endosperm, all of which is covered in a hard protective shell called the seed coating. Fertilization occurred; all that is needed is the proper environment to encourage the embryo to grow. When this occurs, the plant quickly sprouts, first producing stem and leaves for support and the gathering of water and nutrients, as well as the production of energy via photosynthesis.

Roots also grow, absorbing nutrients and moisture from the soil. Transfer of nutrients from the roots to the higher portions of the plant, as well as some transfer of energy from the photosynthesis occurring above the ground to the roots, is facilitated by certain cells within the stem of the plant. The production of flower petals and the plant's reproductive organs occurs last in the plant's life cycle; for some plants this…

Function of Homeostasis in Human Biology

The preservation of stability or constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibria is Homeostasis. (Homeostasis {hohm-ee-oh-stay'-sis}) Homeostasis is the capacity of the body to preserve relative constancy and work even when severe changes occur in the external environment or in one part of the body. (Homeostasis: Toxiocology Tutor III) This is one of the most basic theories in modern biology and this commenced in the 19th century when the French physiologist Claude Bernard observed the consistency of chemical composition and physical properties of blood and other body fluids. He asserted that this arrangement of the milieu interieur was vital for the life of higher organisms. The 20th century American physiologist Walter B. Cannon invented the word homeostasis and he developed and expanded the concept of self-regulating mechanisms in living systems. (Homeostasis {hohm-ee-oh-stay'-sis}) The…

body and the function of Homeostasis

Define the process of homeostasis, then list and explain five homeostatic functions that our bodies perform.

According to Steve Nakoneshny, who quotes a definition from Thibodeau & Patton, homeostasis can be defined as "the relative constancy of the normal body's internal environment."

However, this definition is somewhat incomplete and we should mention the fact that homeostasis, even if generally used when referring to the human body, can also be applied to nature. In this case, it is referred to as ecological homeostasis. Second of all, we should reassert the fact that homeostasis is a condition and not a process, even if it is generally associated with the action.

In order to briefly explain the definition, we should remember the fact that, as any system, the human body has certain parameters between which it functions best. The moment any of these are surpassed, the body…

Homeostasis Defined
Homeostasis, according to Nirmalan and Nirmalan (2017), is the propensity for living organisms to maintain relative stability in the internal environment. Homeostasis is made possible through the cooperation of several regulatory mechanisms and separate sub-systems which make up the normal physiology of a living organism (Nirmalan & Nirmalan, 2017). During critical illnesses internal or external stress can make an attempt at interfering with the self-regulation systems beyond what is considered as normal range in physiology. According to Palaparthi and Med (2017), the word homeostasis is derived from two Greek words i.e. ‘homeo’ (stands for similar) and ‘stasis’ (standing for stable). Homeostasis is the balance, equilibrium and the stability of the body or of the cell (Palaparthi & Med, 2017). Living organisms exhibit this character. The process of maintaining stability in the internal environment necessitates occasional internal adjustments as the environmental conditions continue to change outside and inside the…

Anatomy and Physiology of the Immune System and espiratory System and Their Associated DisordersThe human body is comprised of multiple important systems that keep people alive, including the immune and respiratory systems. These two systems in particular have received a great deal of attention in recent years due to their vulnerability to infections by the Covid-19 virus (Iwasaki & Wong, 2021), but there are a host of other disorders that adversely affect these systems as well. The purpose of this paper is to provide a description of the immune and respiratory systems and the respective physiologies of these two systems. In addition, the paper presents a description of the physiology of these two systems and some of the most common disorders that are associated with them, is followed by an integrative discussion concerning how these systems interact with each other and how they are dependent on each other for proper…

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…

When DNA is damaged, cells can react through cell cycle checkpoints which allows repair to begin before further division can occur. There is also the prokaryotic SOS response which changes gene expression in bacteria as a result of DNA damage. This response is regulated by the production of certain proteins. Moreover, eukaryotic cells also react to DNA damage through producing proteins that begin the process of DNA repair.

8. Mice are often the favored mammalian in the testing of aging interventions. This is often because of the fact that there are many mice easily available for testing but also the fact that "generation time is short" (Yuan et al. 2011). Essentially, the aging process and testing in interventions can be done on a much shorter time scale then with tests using monkeys.

Nurse Speech to Group of esidents in a Large Independent Living Facility

The information addressed today in this speech are those involving the body's regulation of the correct numbers and ratios of blood cells and how blood pressure homeostasis is achieved as well as age-related changes to the heart including coronary artery disease, congestive heart failure and myocardial infarction.

Homeostatis and the Body's Balancing Act

The work of Vikrant and Tiwan (nd) report that studies on the population indicate that blood pressure is a continuous variable and there is really not a line that divides normal and abnormal values. However, there is a point of balance also called internal equilibrium and this is known as homeostasis. This state of balance describes how the human body reacts to certain changes. This can be viewed by picturing a set of scales in which coins are poured in unevenly with one side heavier…

Multisystem Failure in a Geriatric Patient

Multisystem Failure in a Geriatric

eflect on your analysis of the geriatric patient in multisystem failure by doing the following:

Explain key immediate assessments you should make that would help assess the patient's homeostasis, oxygenation, and level of pain.

There are various diagnoses undertaken in assessing the patient's homeostasis, oxygenation, and level of pain. The immediate objective that nurses prioritize on is checking the patient's vital symptoms. Vital symptoms form the baseline of the assessment by providing significant information that illustrates whether the most essential organs function as required.

The assessment may involve checking the health status of the patient in the laboratory (Kane, 2004). In the laboratory, there is an assessment of the patient's capillary tube, urine test and blood pressure. When there is simultaneous malfunctioning of the body organs, nurses refer to this condition as multiple organ dysfunction (MODs).

Multiple organ dysfunction…

The blood in which we are traveling in is composed of red blood cells called hemoglobin, plasma, platelets, and white blood cells. Blood is transported through the body by the heart's pumping action. As we continue, we will enter the hepatic portal vein, which delivers blood from the gastrointestinal tract to the liver, into the ascending aorta, up towards the heart. As we approach the heart, it's pumping will pull us up into its chambers and through to the lungs where we will get oxygen and continue our journey to the kidneys. As we return to the heart, we will pass through the aortic arch and descend through the thoracic aorta continuing past the descending abdominal aorta until we reach the renal artery. We will make a left turn and pass through the glomeruli through the kidney's tubules and conclude this phase of our journey into the left kidney.

Homeostasis is the goal promoted by both positive and negative
feedback mechanisms. This is the principle which indicates that there is a
balance in autonomic life functions which the body attempts always to
maintain. This refers to such features as body temperature, heart rate,
respiration and the powering of vital organs. When stimuli create a
divergence from this status, the body will activate a set of responses
designed to regulate a return to balance.

There are three major anatomical planes, which are used to refer to
different ways of addressing the body and its systems. The anatomical
planes include the Coronal Plane, which refers to the frontal surface of
the body from head to foot. The Sagittal Plan refers to the surface which
might be viewed from a profile, indicating a lateral perspective on the…

However, it was 1953 that the formation of serotonin was from the lungs was substantiated. It is also observed that detoxification of the blood takes place in the lungs. Later, it was observed that one of the important activities of the lung is to provide chemical filtration by shielding the regular circulation of blood from the attack of vasoactive mixtures and other exogenous compounds present in the arteries. The physiology of the lungs and its location makes the lung exclusively suitable to perform these activities. (Wet; Moss, 1998)

The total output from the cardiac system is obtained by the lungs whereas other organs acquire only a very small quantity of output. The blood that circulates the lungs is subject to the vast capillary endothelial plane of the body which is of seventy square meters. This aspect of output and circulation enable the lung to perform the efficient function of biochemical…

The Breath of Life

Throughout scripture the concept of breath represents life. Genesis 2:7

It is evident that we need to breathe to live and that without our respiratory system, we would die. But why is this? Can we know why other than to say that this is how our Creator designed us to be? Perhaps an understanding of our own respiratory system can help us to better understand our Creator? I think so.

What do we find in our nose? A kind of filter that keeps out of our lungs harmful particles and spores that would otherwise pollute them. This can be a symbol of how we should filter our minds of impure thoughts so as to keep our souls clean. It can also be a symbol of how important God's grace is in our souls -- it is to our souls as oxygen is to our bodies.…

The success was remarkable, according to the researchers: Even muscles that had already lost half of its mass, recovered visible. (Leppanen et al. p5549-65) At the same time, the mice survived for several weeks longer than their untreated counterparts and also developed a healthy appetite again. (Mantovani, p296) The new study is therefore interesting in two respects: First, it demonstrates that the muscle loss at least in animal models in fact, affects the chances of survival, and secondly, it shows a way, may be how to prevent this degradation, and even reversed. (Bruera et al. p857)

Muscle atrophy

Muscle atrophy is a medical term that refers to the decrease in the size of skeletal muscle, losing muscle strength because of the strength of muscle is related to its mass. (Burnfoot, p323-34)

Homeostatis, a term which refers to the maintenance of the internal state of a given body that is quite distinct from the external environment in an effort of defending it against perturbation is an important element of every male and female on the planet. In this paper we attempt to explain how homeostatic mechanisms affect the homeostasis of the eproductive system.

How homeostatic mechanisms affect the male reproductive system

The hypothalamus produces the hormone gonadotropin-releasing hormone (GnH) which controls the anterior pituitary gonadotropins. The anterior pituitary gonadotropins then releases Folicle stimulating hormone (FSH) and Luteinizing hormone (LH).The Folicle stimulating hormone (FSH) then indirectly stimulates spermatogenesis by simulating sustentacular cells to effectively release andogen-binding protein (ABP).The andogen-binding protein (ABP)

then prompts the spermatogenic cells to effectively bind while also concentrating testosterone which then stimulates spermatogenesis.

The Luteinizing hormone (LH) effectively binds to the interstitial cells which then secretes testosterone and a…

Lymphatic system is a sub-system of the circulatory system. It contains a network of nodes, or vessels and filters, which remove toxins from the body. The role of the lymphatic system in the homeostasis of the body is that it serves as the primary drainage for all of the body's other systems, removing all toxins and excess fluids. It is a major defense against disease and also helps carry nutrients throughout the body.

The lymphatic system does not circulate blood. Lymph is its primary fluid and is formed from fluids surround cells throughout the body and passed into lymph vessels. If this fluid were not removed or filtered, the result would be toxins accumulating in the body. This would create swelling and also prevent the body from fighting against infection and disease.

Disorders or complications originated in the lymphatic system create serious illness in the body. This is because this…

Drive Theory

Woodworth's Drive Theory Applied

One of the theories of human motivation that was developed in the first half of the twentieth century by psychologist obert Woodworth is the drive theory, or more specifically the drive theory based on an assumption of basic homeostasis and the biological desire to maintain this homeostasis (Halvers 2011; Eysenck 2000). Simply put, this theory asserts that humans are driven to satisfy their biological needs and maintain homeostasis by taking care of basic needs like hunger, thirst, and other physical and physiological needs (Vigori 2011). According to this theory, when these needs are not being met the lack of homeostasis triggers a response that creates a conscious impulse or motivation on the part of the individual, leading to conscious actions that attempt to satisfy the conscious desire and thus the subconscious need by restoring homeostasis (Halvers 2011).

One situation in which this theory of…

The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood.

The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within the heart's lower half, are responsible for pumping blood to the whole body (away from our heart), whilst the atria, situated within the heart's upper half are in charge of receiving blood from different parts of the human body. The right and left ventricles pump de-oxygenated and oxygenated blood, respectively; de-oxygenated blood is pumped to lungs while oxygenated blood is pumped to the remainder of the human body (smith, 2013). These 4 chambers are connected to one another by…

Hypnosis

In his study, "Cognitive Hypnotherapy in the Management of Pain," Dowd (2001) reports that, "Several theories have een proposed to account for the effect of hypnosis. State theories assume that the hypnotic trance is qualitatively different from all other human experiences. From this perspective, trance capacity is supposedly a fairly stale trait that exhiits sustantial individual differences. Nonstate theories, often referred to as social learning, social psychological or cognitive-ehavioral theories of hypnosis propose that hypnotic phenomena are related to social and psychological characteristics such as hope, motivation, expectancy, elief in the therapist, desire to please the therapist, a positive initial…

Counterbalance of Sugar and Fat Content between Insulin and Glucagon

Physical survival depends on the sustained availability and use of energy in the form of adenosine triphosphate or ATP from sufficient levels of a substance, called glucose (owen, 2001). The use of energy depends on the varying levels of activity. Hence, the amount of glucose needed for activity likewise varies each day. Too much or too little glucose is damaging to the body, hence the need for some system to regulate the availability of glucose. It must be present at the precise time and amount that it is needed in order to maintain what is called glucose homeostasis. Homeostasis is the tendency of the body to maintain internal stability and balance through the coordinated responses of body parts to stimuli or conditions (owen).

Insulin and Glucagon

The regulation of glucose availability begins with the pancreas, primarily by…

Briefly explain the following concepts with an example each:
i. Fight-or-flight response
Fight-or-flight response refers to the dynamics that encompass the physiological arousal of the body to survive a threat. In preparation for a threat, there are two immediate actions that one can take: either attack or fight for defense from the threat or opt to run and flee away from the threat. For example, when a person encounters a barking dog while running, the fight-or-flight response runs away or faces the dog (Seaward, 2015).
ii. Holistic medicine
Holistic medicine alludes to an approach of healing that honors the assimilation, counterbalance, and synchronization of mind, body, spirit, and emotions for encouraging internal peace. It is an attitudinal method to healthcare instead of a certain set of techniques (Gordon, 1982). Examples of holistic medicine comprise homeopathy, acupuncture, and also massage therapy.
iii. Stress reaction

The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them for elimination from the body. The perspiration or sweat is then removed through the sweat pore. This has a twofold purpose: to remove toxins and thermoregulation (in this case cooling the body).

Thermoregulation involving perspiration is brought about by both internal and environmental heat and exercise. As it relates to the latter, there have been many studies related to exercise and thermoregulation. According to Marino (2004)

"thermoregulatory effector responses of humans and concluded that temperature regulation during exercise is dissimilar…

Symbolic interactionalism thus posits a much more dynamic view of human learning, rather than the rote reception of societal norms in functionalism, or functionalism's belief in education to shape human minds in a pre-determined fashion. But it also is a more positive view of education than conflict theory, because even if there are problematic ideas in the way knowledge is conveyed, human beings may be creative enough to reconfigure preexisting systems of meaning in a liberating fashion. Also it is the individual who chooses how his or her personal liberation and development should take place, not the teacher. "Symbolic interactionalism emphasized several important dimensions of knowledge management through schooling: in school classroom interaction; by the professionalizing of the teaching process; through the bureaucratization of school organization; and, at the cultural level, where the links between the sociology of education and the sociology of knowledge are more immediately visible" (Marshall 1998).…

role of hormones in the control of body fuel/energy mechanism has been appreciated for close to a century (Dzamko & Steinberg,2009). This concept was identified by the groundbreaking findings by the scientists, Banting et al. (1922) that the hormone, insulin could effectively restore euglycaemia. This paper seeks to give an in depth understanding of metabolism by definition and gives the various component of metabolism and finally the hormonal influence of metabolism. This paper looks into the various substrates that are influence the hormonal actions in fuel metabolism, circumstances under which they occur and the various pathways followed during these metabolisms (Becker, 2001). The intermediary compounds are also considered to the effect. In conclusion, the paper discuses the medical conditions that would arise once these hormones fail to act.

This lack of ADH makes the collecting duct impermeable to water (www.nmc.edu/~koverbaugh/bio106/su02/chapt15.htm)." ADH production decreases when alcohol is consumed, resulting in dehydration.

When there is a low blood volume, the "juxtaglomerular apparatus secretes enin, leading to Angiotensinogen, Angiotensin I, and Angiotensin II. Angiotensin II causes the adrenal gland to secrete aldosterone, which increases the return of Na to blood. This increased salt in the blood causes water to diffuse into the blood from the urine (www.nmc.edu/~koverbaugh/bio106/su02/chapt15.htm)." The secretion of aldosterone is "also triggered when potassium levels are elevated (hyperkalemia), and through the sodium-potassium pump, it increases potassium excretion while increasing sodium reabsorption (http://www.dacc.edu/~lgarret/fluid.html)."

Conclusion

Alcohol consumption negatively affects the urinary system by decreasing the production of ADH. This reduction of ADH will cause the body to become dehydrated, and can lead to electrolyte imbalance.

Osmoregulation

Endocrines Osmoregulation

Osmoregulation is the process, by which the body adjusts to a change in an environment of different water volume and amount of solutes in a cells and body fluid of organisms including vertebrates. Vertebrates are animals, which have a backbone, and can be warm either blooded or cold blooded. The body of such organisms adjusts in order to maintain the body balance both inside and outside their bodies in mild and harsh environments ranging from seawater, fresh water, and terrestrial habitats to very hostile environments. Endocrine glands found in such organisms play a major role in constant and persistent regulation of body balance, which secretes hormones directly into the blood whenever the body witnesses any environmental change (Bentley 45).

Endocrine glands present in vertebrates play a major role in controlling the level of water and salt in vertebrate's bodies. Hormones produced in vertebrates play a major role…

Cold War between the United States and the Soviet Union is known as such because it was waged not through direct conflict, but in through military and political stand-off between nations. On an international level, the Cold War was waged through techniques such as the U.S.S.R. extending its sphere of influence into Eastern Europe and the United States' Berlin airlift. However, its effects were also felt inside the United States, with the hysteria that resulted in the form of McCarthyism and the often-obsessive fear people expressed in regards to protecting themselves from possible nuclear conflict. The hatred an American expressed for communism was used to validate his or her status as a 'real' American. This line of reasoning can be seen today in issues of discrimination against Arabs and other demonized ethnic groups, as well as upon moral issues as abortion and gay parenting. One's stance on these issues is…

The collaborative team here would consist of a primary care physician / geriatrician, pain management specialist, laboratory specialists, and x-ray team. Additional consultants may be neurologist, neurosurgeon, gastroenterologist, psychologist, and drug and alcohol detoxification specialist.

In the case of increasing respiratory distress, the nurse is advised to continue or modify the interventions: to continue to teach patient how to breath and cough correctly; to summon a productive cough; to attempt to clear lungs to auscultation; and to achieve symmetric chest excursion of at least 4 cm; also that her respirations and pulse beats should be regular, and that she should inhale a normal volume of air. This is done by encouraging Fowler or semi-Fowler's position; monitoring…

What management does still exists must maintain an open door policy, so as to help lower level employees transition and communicate concerns but again managers are likely to have a clear idea that this is a behavioral manner of influencing actions. (Tyler, 1997, p. 323)

Though the transition to flat organisation may benefit most organisations, it is still a transitional situation that requires special understanding of employee empowerment as well as interactions. Smaller firms of coarse will find this transition easier while larger firms may need to create quasi-flat systems that better serve multi-factorial production systems and require the system to work together in a streamlines fashion, without one area of production causing unintended problems for another. Employee empowerment is clearly one of the biggest reasons why employees express happiness and comfort within a system and therefore create active retention and motivated work.

Calcium is needed in blood clotting, stability and permeability of the membrane, nerve conduction, muscle contraction, cellular secretion, enzyme activity, and cell growth. Magnesium is needed for the metabolism of potassium and calcium and for the mobilization of calcium from bones. Phosphorus plays and important role in the development and maturation of the bone. Its chief role in bone resorption, mineralization and collagen synthesis makes it essential in calcium homeostasis (Michael's).

Maslow gave them that self-meaning and appreciation and became one of the pioneers of a movement that brought the focus of individual feeling, yearning and wholeness into psychology. He sort of read them out and spoke their thoughts, feelings and aspirations for them. He devoted much energy to humanistic psychology and the human potential and inaugurated the "fourth force" in psychology towards the end of his life. The first force consisted of Freud and other depth psychologists; the second force, the behaviorists; his own humanism and European existentialism, the third. This fourth force was made up of transpersonal psychologies that derived from European philosophies, which examined meditation, higher consciousness levels and para-psychological phenomena and which reacted against the then dominant psychoanalysis and behaviorism schools of the 20th century. Among the most prominent European philosophers were Kierkegaard, Husserl and Heidegger and the most prominent in the humanist/existential group were Carl Rogers,…

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

Myra Levine Nursing

easons why the MYA LEVINE NUSE theorist developed the theory

Myra Levine an influential figure in the nursing vocation set up new methods which were effective for educating the nursing degrees students with fundamental concepts and caring, of the patients (Parse 2009). Her objective was to present individualized and reactive care of the patients which concentrated less on medical procedures and maximized on individual contexts of the patients. With this, it led to nursery theory's creation and patient care approach. The theory implies criteria which help in evaluating the nurses and what to do.

It offers concepts which are skilled in sustaining research which are useful to the nurses. Hence, it creates knowledge which is exclusive to the nurses. By that, it enhances the nurse's status as a better profession. In promoting the research, the nurses' theory endorses the education of the nurse (Allan 2011). With that,…

Myra Levine

Nurses and patients are engaged in a "partnership of human experience," (Levine, 1977, p. 845). The ethical obligations and core values of nursing are rooted in this fundamental assumption about the relationship between nurse and patient. Nursing entails ethical obligations. "To be a nurse requires the willing assumption of ethical responsibility in every dimension of practice," (Levine, 1977, p. 845). The ethical obligations of a nurse are best explained by the belief that patients are holistic beings who constantly "thrive to preserve wholeness and integrity," ("Levine's Four Conservation Principles," 2012). Each patient is unique, too, and each seeks wholeness in a unique way. Nursing is defined as "a human interaction designed to promote 'wholeness' through adaptation." Myra Levine's theory is patient-centered, rather than disease-centered; the patient is treated and not just the disease. Because it offers specific guidelines within a rubric of ethical and philosophical tenets, Levine's conceptual…

Motivation

Many psychologists have put forward theories to advance the concept of motivation. Some of the psychological theories and models that explain motivation include incentive theory, drive theory, self-control model, push and pull model, intrinsic and extrinsic model, and rational motivations among others. Motivation stems from a number of sources, which dictate the way a person acts. It is paramount to note that motivation is one of the greatest determinants of motivation, and one can tell the level of motivation of a person through the way one behaves. The discussion below is an insight into this concept for a better understanding of motivation.

Motivation is a term in psychology that is hard to define; a number of theories have different views of motivation. These views of motivation include drive theories, incentive theories, and homeostasis, and one can draw a common definition of motivation from these views (Kalat, 2011). According to…

Obasan, Oppression, & emembrance

Children whose parents survived the Holocaust often report that their parents spent their entire lives attempting to conceal the fact that they were persecuted, had narrow escapes, and -- for many survivors -- were interred in concentration camps. The desire to protect their children from the horrors they experienced is certainly one of the reasons that survivors give for their silence. But their silence also enables them to keep their fears, anxieties, and regrets at bay, at least for those brief periods of time when forgetting has its intended effect. In effect, the reluctance of survivors to remember puts up a barrier that neither generation can easily cross -- not the generation of survivors, who have grown old in the years that have passed since World War II, and not the generation of children who have managed not to ask too many questions or follow their…

blood ion levels, particularly sodium, potassium, and calcium levels, if there is a decrease in overall blood flow to the kidneys. A full credit answer will discuss the mechanisms at the cellular and chemical level.

Kidney failure: What occurs when there is a decrease in blood flow to the kidneys?

A decrease in blood flow to the kidneys can lead to complete organ failure at worst or at minimum severely disrupt the body's state of homeostasis. The kidneys play a critical role in the regulation of electrolytes, particularly sodium, potassium, and calcium. As their name suggests electrolytes, or ions, "are the charged particles in body fluids that help transmit electrical impulses for proper nerve, heart, and muscle function" (Astle 2005). In a healthy organism, positive and negative ions are in a state of equal balance. Decrease in blood flow to the kidneys severely disrupts the body's ability to not only…

ethics and morality of Paul Taylor's view of the environment

One key ethical issue, contentious amongst environmentalists today as well as those activists who oppose the ethical philosophy of environmentalism, is whether environmentalism should be focused on improving the lot of the human animal on earth, or should attempt to benefit all species upon earth in an equal fashion. The philosopher Paul Taylor argues that environmental ethics should emphasize the interdependent nature all individual members of earth's biological community. He states that environmentalists should embrace the idea that no single species is superior to the others. However, although Paul Taylor's philosophy is commendable in its emotional intensity when he says, "we have a self-evident moral obligation to the individual members of the Earth's biotic community to protect and promote their good for their sake" (518), his philosophy of species equality is fundamentally flawed. Environmentalism is a human ideological construction. No…

Open Systems. What would you consider to be the advantages of these characteristics?

One major characteristic of an open system is the importation of energy: "No human organization is self-contained or self-sufficient; thus, it must draw energy from outside to ensure survival. Take the case of a consulting firm that specializes in conducting employee opinion surveys for client organizations" (Von Bertalanffy et al., ). The consulting firm in this example is constantly drawing upon outside energy from the surrounding environment in order to fulfill its obligations and the needs of its customers. The second major characteristic is "negative entropy" which states that all organizations move naturally to the state of disorganization or death, but it is through the concerted action of all involved through importing energy via the environment that one can combat the evolution to this natural state (Von Bertalanffy et al., 1950). Another trait is that of the…

MASLOW'S THOEY VS. HULL'S THEOY

Integrating Two Theories of Motivational Psychology

Maslow Hierarchy of needs vs. Hull's Drive eduction Theory

Motivation is common term, but it is not easily defined. This is due to the many studies, which provide different definitions for the term. While some define it as a set of beliefs, values, interests, others define it as a cognitive decision making process. For this paper, motivation is central to a set of processes, which induce, direct, and maintain actions towards an objective. It is not similar to job performance, but it is a contributor to job performance (Linder, 1980). Motivation is a crucial component in the workplace, which explains why organizations are borrowing concepts from the motivation theories. There are many motivational theories, but they either fall under the content or process categories. Content theories assume that individuals have similar needs, and process theories emphasize the importance of…

Thyroid and Hormones

In some ways, the thyroid, parathyroid, aldosterone, and antidiuretic hormone (also known as ADH) all contribute to similar types of effects on the body, since they are either glands that secrete hormones or actual hormones themselves. Hormones help to regulate processes in the body. Many of the aforementioned glands and hormones regulate processes that pertain to water and electrolytes either directly or indirectly. The thyroid is one of the most sizable endocrine glands existent within the body and is located in the neck in the area that is close to where one's Adam's apple is (Tweed, 2015, p. 46). The thyroid plays an invaluable role in the regulation of other hormones because it essentially controls how responsive the body is to other hormones. Therefore, in terms of electrolytes and other types of energy that may be gained from conventional food and drink sources (such as water), the…

Aging can be defined as the buildup of damage in molecules, tissues, and cells throughout an individual's lifetime. As a result of this accumulation, the capacity of an organism to sustain homeostasis in stress situations is decreased and enhanced risk for many diseases emerges (Rodriguez-Rodero et al., 2011). The process of aging, which is commonly known as senescence, affects people in different ways because of its varying impact on different parts of the body and at varying rates (Zastrow & Kirst-Ashman, 2016). Given these differences, the aging process is different between individuals as some seemingly age faster than others.

There are several factors that affect the aging process and contribute to the differences through which some people seem to age faster than others. One of the major factors that affect the aging process is cell aging, which entails DNA damage and telomeres. In this case, aging is a by-product of…

Drugs thought to enhance serotonin-mediated neurotransmission have been shown to diminish appetite for carbohydrates. In a study done by Heraief, Burckhardt, Wurtman and Wurtman, (1985), they examined the ability of tryptophan (TP), serotonin's amino acid precursor, or a placebo to influence weight loss among 62 obese Swiss outpatients who were on a reducing diet known as the Protein-Sparing Modified Fast (PSMF) Diet which is often associated with severe carbohydrate craving. This diet provided relatively large amounts of protein but little carbohydrates, thus stimulating ketone body production. Its consumption also reduced the ratio of plasma TP to the summed concentrations of the other large neutral amino acids, thereby probably diminishing brain TP and serotonin levels. It was found that among moderately obese patients the TP significantly enhanced weight loss, especially during the first treatment month but also during the total. The TP didn't modify the reported adherence to the PSMF diet.…

Lipases digest fat and fat soluble vitamins. Enzyme.com reports, "Lipase deficient people have decreased cell permeability, meaning nutrients cannot get in and the waste cannot get out of the cell. For example, diabetics are lipase deficient and cannot get glucose into their cells, and wastes or unwanted substances cannot get out." Heart disease can come from this.

Cellulase deficiency can lead to sugar or gluten intolerance. Enzyme.com writes, "Cellulase deficiency is a malabsorption syndrome (impaired absorption of nutrients, vitamins, or minerals from the diet by the lining of the small intestine) with its many symptoms of lower abdominal gas, pain, bloating and problems associated with the jejunum and pancreas as well as nervous system conditions such as ell's Palsy, Tic and facial neuralgia."

Ethnicity can be related to deficiencies of the body. Emedicine.medscape.com (2010) reports, "Congenital sucrase-isomaltase deficiency is most common in Canadian Eskimos and natives of Greenland. They cannot…

The stress alarm, therefore, can actually assist the employee to improve her performance and is necessary especially, if positive perceptions regarding the challenges of the work environment exist. The response to the stress under the Cognitive Activation Theory of Stress, provided that the exceptions held by the employee are positive, is healthy and necessary for survival and productivity. Eriksen H.., Murison, ., Pensgaard, a.M., Ursin, H. (2005). Under this theory, emotional and physical health within the individual is sustained through a positive expectation for the outcomes, compliance with the expectations, or through resisting the stress altogether. Eriksen H.., Murison, ., Pensgaard, a.M., Ursin, H. (2005). A summary chart outlining these different theories on stress and their potential effects on the organization follows.

However, recently, anesthesiologists have suggest a low to mid thoracic epidural combined with adequate general anesthesia. This anesthetic technique will allow for adequate inter-operative monitoring. After the operation, the anesthesiologist must continue to monitor the patient for either hypertension, hypotension and hypoglycemia. The presence of either of these conditions may alter the course of the medication given to the patient once the patient is removed from the anesthesia.

Respiratory System

Neurofibroma can cause systemic problems within the various components of the Respiratory System. As has already been presented, Neurofibromas can cause partial blockages within upper parts of the trachea. However, Neurofibromas can also pose challenges or the anesthesiologist when dealing with nasal, sinus or maxilofacial cavities with Neurofibromas present within. One example of how devastatingly complex the Neurofibroma can become is seen when a benign neurofibroma can cause a superior vena cava compression. Such was the case of a 21-year-old…

The Tasman Spirit crew and financiers should work to investigate acute health concerns as well as the marine ecosystem surrounding Karachai. The American Club, likely one of two involved parties with the financial resources to affect significant change in the region which actually suffered the effects of the environmental disaster. ather than working against each other with suits and counter suits and the assorted other motions and legal actions underway, it would be most effective and positive for those two companies to work together with environmental awareness and protection agencies to restore the region.

This portion of the analysis is concerned with the specific affected individual parties. While it is important not to allow empathy for a specific group to outweigh the impartiality of an effective analysis it is also important to understand the relevant human components of a situation especially one which has such a…

The brain can be understood in terms of its lobe-like structures, or it can be mapped out according to the regions that seem to dictate and influence certain behaviors and processes. The three major areas of the brain in this schema are the motor areas, the sensory areas, and the association areas, though in reality almost all human functions and behaviors involve interactions between these areas. Interestingly, large and imprecise movements have been found to originate in a very small space of the motor areas, whereas more precise yet much smaller movements require large brain areas. The sensory area consists of three composite areas -- the somatosensory area, the auditory area, and the visual area.

pp. 87-8

The association areas of the brain are believed to control higher-level thinking and processes that regulate behavior in a larger sense, such as turning Phineas Gage from a hardworking and responsible…

The primary organ that is accountable for regulating metabolism is the hypothalamus. The hypothalamus is situated on the brain stem and forms the floor and part of the lateral walls of the third ventricle of the cerebrum. The main functions of the hypothalamus is to control and integrate activities of the autonomic nervous system (ANS), production and regulation of feelings of rage and aggression, regulation of body temperature and regulation of food intake (Graham, 2005).

BM goes down with age and with the loss of lean body mass. Increased muscle mass and cardiovascular exercise can help to increase BM, even when the body is at rest. Measured in calories, metabolic rates vary with exertion, recent food ingestion, muscle exertion, environmental temperature, emotional state, body temperature, pregnancy, menstruation, level of thyroid hormones stress hormones (epinephrine and norepinephrine), fear and illness. The human body requires energy in order to stay alive…

As the road is being laid the fumes from the chemical materials and the concussive force of the construction equipment are devastating to local wildlife (Forman & Alexander, 1998). The result, is displaced organisms which ultimately put increased pressure for food, land, and water on other ecosystems. The extent of these ripple effects are still yet to be fully known.

In instances where above or below ground water supplies must be altered in order to make way for a new road system the effects are if anything more dire. When laying the bed of a road, it is nearly impossible to prevent a percentage of the chemicals used in the road surface itself from leeching into the soil (Forman & Deblinger, 2000). When in the presence of water those toxins are carried the course of the water supply affecting all of the vegetation and wildlife which it comes into contact…

An interesting view of the immune system with particular implications for the current review and collation of information is provided by the field of computer science. The immune system makes many series of continual trade-offs, distributing resources in a way that necessarily leaves certain vulnerabilities in the system as a whole while providing greater comprehensiveness in coverage and protection when necessary (Hofmeyr 1997). This makes the immune system an adaptive and continually evolving and self-improving system; with little outside direction it is capable of assessing changing needs, and altering itself not only in particular instances but even in some of its general responses in order to provide greater long-term efficacy for the task of protecting the human organism from disease (Hofmeyr 1997). This view of the immune system as a contained and self-informing system is not entirely accurate, but it is a very useful perspective for our purposes herein.

Notwithstanding the challenges involved, the stakes are high and there is little room for false starts or experimentation; therefore, identifying a general set of best practices that Gambian organizations can follow in developing their own set of sustainable productivity practices represents a valuable and timely undertaking, which relates to the purpose of the study which is discussed further below.

Purpose of Study

The overall purpose of this study was to study to provide a review of the relevant juried and scholarly literature together with the findings of a survey of Gambian business leaders to generally identify the most pressing priorities for developing the nation's infrastructure and sustainable organizational productivity. The specific purpose of the study was to determine whether SMEs face the same types of challenges of to optimum performance as their larger corporate counterparts, and to identify any peculiar organizational characteristics that determine levels of performance between SMEs and…

Q3. Explain the role of an Indian band leader (known as sachem or sagamore). How did he gain and keep his position? What were his duties and how did the value of reciprocity function in his relationship with the band? Explain who pnieses and powwows were.

The sagamore or sachem's primary duties were to mediate between clans and to engage in inter-tribal diplomacy. Anything that required greater coordination efforts beyond that of families or clans, such as large-scale hunting, was the sachem's responsibility. The European observers were often horrified that the sachem's position depended upon the collective will of the people, versus that of European monarchs, the latter of whom ruled by force and heredity, Some sagamores did claim to have shamanistic powers that caused them to be more "dreaded" (Salisbury 44). However, most sagamores depended upon counsels of pnieses and powwows, which were made up of other members of…

In this regard, Demorest concludes that, "Together these and other theorists have provided accounts of what it means to be a person that all fit within the psychodynamic paradigm, a perspective that holds a vision of people as at their core driven by dynamic forces in their unconscious minds" (2005, p. 3).

Freud's influence on psychoanalytic thought, though, required some time to take hold and many of his methods were rejected outright by the contemporary medical establishment, particularly in the United States. For example, following Freud's only trip to North America in 1909, one psychiatrist believed that, "Many patients were psychotically disturbed and deemed to be beyond the reach of Freud's intellectual 'talk therapy'" (Beam, 2001, p. 94). Not only did others think that Freud's methods were not appropriate for some patients, Freud himself acknowledged their limitations. In fact, Beam points out as well that, "Freud himself thought most schizophrenics…
