Hormonal Regulation of Urine
Human beings are made of 75% water. The huge percentage of water in the human body is attributed to the constant need to sustain fluid balance through drinking water. However, the quantity of ingested water needs to be balanced with the amount and concentration of urine generated so as to regulate the volume of fluid and osmolarity within an ordinary range. Urine is formed in the human body through three major processes that occur in the nephrons i.e. glomerular filtration, tubular reabsorption, and turbular secretion (McCann et. al., 2002, p.605). The quantities of substances reabsorbed and secreted in the nephrons are varied by the kidneys, which contributes to changes in the composition of excreted urine.
Urine output or excretion is usually regulated by several hormones that also play a crucial role in regulation of urine. Vasopressin is one of the hormones that regulate urine output and is regarded as the hormonal mechanism for controlling the output of urine. This hormonal mechanism is excreted from the posterior pituitary gland that is directly linked to the magnocellular cells of the supraoptic nucleus and paraventricular nucleus. Through activating aquaporins, vasopressin acts on the renal by gathering duct to improve the reabsorption of water. Aquaporins are proteins with water channels that...
Myxedema is a potentially deadly endocrine regulation disease that usually arises in connection with pre-existing hypothyroidism, when the normal homeostatic mechanisms for responding to hypothyroidism are overwhelmed. It occurs most often in elderly women, and is usually characterized by swelling of the skin and other soft tissues (Wall, 2000). The thyroid gland is central to homeostatic metabolic functions, and operates as part of a complex feedback loop involving both the pituitary
Renal Failure Main Functions of the Kidneys The kidneys are bean-shaped organs, 12 centimeters long, which lie at the sides of the spinal column behind the abdominal cavity (Merck 2010). Their main function is to maintain the proper balance of water and minerals in the body. Their other major functions include filtration and elimination of wastes and toxins, regulation of blood pressure and secretion of some hormones. The amount of water taken
Water: The Only Liquid the Body Needs To live a fully healthy and functional life, water is indispensible. From the point in history when primitive species moved from the oceans to land, a major factor of survival has continually been stopping dehydration. The important adaptations that enable this are present in almost all species of animals, including man. Water makes up varying percentages of the body weight of humans from 75%
Critical Pathway: Chronic Renal Failure Advanced Pathophysiology Regents Online Degree Program Critical Pathway: Chronic renal failure Chronic renal failure is often occasioned by chronic kidney disease, immune disorder, trauma among other conditions. It does not have any specific symptoms and might include feeling unwell generally and experiencing a reduced appetite. It is diagnosed following screening of individuals who are identified to be at risk of kidney problems, like individuals with diabetes or high blood
Hypertension Management � Synthesis of Literature, Practice Recommendations, and Evidence-Based Practice VerificationHypertension, or high blood pressure, is a growing global health crisis affecting over one billion people worldwide. It's a silent but significant contributor to cardiovascular diseases, stroke, kidney failure, and other serious complications, claiming millions of lives each year. Blood pressure is the force created by your blood as it pumps through your arteries. When this pressure is consistently
Case Study: JasonIntroductionThis case study is of a 28-year-old male who has been transferred from the psychiatric unit to the acute hospital after three episodes of tonic-clonic seizure with subsequent altered conscious state. The purpose of the study is to provide details of the presenting problem, the health assessment, a critical evaluation of diagnostic investigations, clinical manifestations, aetiology and pathophysiology, interventions, and relevant evaluations.Patient Demographics and HistoryJason is a 28-year-old
