Anatomy of the Heart
I am positive that there could never ever be
An organ so very intimately connected to me
(as my heart…)
How sweetly, reliably my heart keeps me alive
Circulating my life-sustaining blood, helping me thrive..
(Thank you my heart…)
It started wall before I was born -- working every day
Bringing oxygen-poor blood to my heart's foyer
(Known to biology as the right atrium…)'
Like a cool breeze in the desert, it was a miracle
Pumping my blood to the right ventricle
(Thank you veins for your stewardship…)
And from the ventricle the blood enters my lungs
Another step on the ladder of life, higher rungs
(I trust my lungs….)
In my healthy pink lungs oxygen permeates
Reviving tired blood -- it kind of resituates
(if only the world worked this way!)
Back into my heart the freshly oxygenated blood flows
Into my left atrium, as every knowledgeable person knows
(Thank you, thank you, white and red cells)
Arriving in the left ventricle with its renewed strength
The miracle continues and I could go to any length
(to praise this amazing organ for keeping me alive…)
The left ventricle pumps reinvigorated blood to my brain
And throughout my body, to every single artery and vein
(I promise to stay healthy and keep my body strong…)
Scientists and doctors tell us to avoid too much animal meat
Because our precious arteries suffer when too much fat we eat
(Vegetables and fruits should replace burgers often…)
The way to live long, healthy lives is to respect the heart
Because from our loved ones and friends we don't want to part
(a steady diet of fatty foods leads us to mortality…)
So now you know, how matters of the heart relate
And for those with bad dietary habits -- hey, it's never too late!
(Take care of your heart -- it takes care of you…)
(Ibid). Identify all components of a normal ECG rhythm- a typical, or normal ECG tracing of the heartbeat consists of a P. wave, a QRS complex, a T. wave and a U. wave (visible in 50-75% of cases). Identify basic ECG rhythms -- ECG rhythms are printed on graph paper, the smaller squares represent .04 second; 1 second 25 small squares, etc. The basic rhythms are: (Source: ECG Tutorial, 2006). Identify basic dysrhythmias
Even though the heart works harder, blockages still shortchange the needed blood supply to all areas of the body. Kidney disorders, which leave extra fluids, sodium, and toxins in the body, obesity, diabetes, birth control pills, pregnancy, smoking, excess alcohol, stress, and thyroid and adrenal gland problems can also cause and exacerbate a high blood pressure condition. Proper ranges of cholesterol are also important in the prevention of heart attack
Anatomy and Physiology Sickle cell anemia is defined as being a severe form of the illness anemia, where not enough healthy red blood cells are present to carry the necessary oxygen to the rest of the body (Hwang & Shaparin 2003). Red blood cells in individuals with sickle cell anemia will be rigid and moon-shaped, unlike normal red blood cells that are smooth and round. Because of the shape of the
Macabasco-O'Connell et.al say that the stress levels for women in this group is oftentimes higher than non-minority women in higher socioeconomic groups. The high amount of stress that these women experience is usually accompanied with depression and studies have shown that depression can also lead to a greater risk of heart disease (2, 3). Because many women from lower socio-economic statuses are uninsured or underinsured, they run the risk
The oxygen attaches to the blood cells and this is the means by which oxygenated blood returns to the body. We are investigating the lower lobe of the right lung. This part of the lung is generally free from bacteria and that is the case here; our human is healthy. Nonspecific immunity refers to the mechanisms the body uses collaboratively with other systems. In the lower lobe, the spongy outside
When an heart needs more oxygen, such in times of exercise, stress or pharmacological stimuli, blood flow is increased to fulfill this demand. However, the physiological narrowing of arteries due to plaque build up found in coronary disease restricts blood flow to the heart, especially in times of when an increase in myocardial oxygen is needed. These restrictions mean a lessened CFR for the individual, which can lead to
