The purpose of the heart is to pump blood to the body in order to nourish it. Heart failure doesn't mean that the heart has stopped working, but that it just isn't able to pump enough blood to meet the needs of the body. This may happen when the heart muscle itself is weaker than normal or when there is a defect in the heart that prevents blood from getting out into the circulation. When the heart does not circulate blood normally, the kidneys receive less blood and filter less fluid out of the circulation

Congestive Heart Failure Congestive heart failure, or CHF, is a condition that afflicts millions of Americans. Over five hundred thousand new diagnoses are made every year. CHF is a condition that is entirely caused by the body’s homeostatic compensatory mechanisms. CHF arises from the condition simply termed, heart failure. Heart failure is manifested by the heart’s inability to provide adequate perfusion to the body. This occurs due to other conditions or diseases such as chronic hypertension

system. Our heart is a strong muscle that beats about 100,000 times a day. With each beat of the heart, blood is pumped to the lungs via pulmonary circulation and to the rest of the body via systemic circulation. The pumping of the heart enables the body to receive oxygen and rid the body of carbon dioxide. Your heart pumps 30 times its own weight each minute. This amounts to about 5 liters of blood pumped to the lungs and to the rest of your body. It is, therefore understandable why the heart changes

with APA guidelines. Scenario A Acute renal failure: Ms. Jones, a 68-year-old female, underwent open-heart surgery to replace several blocked vessels in her heart. On her first day postoperatively, it was noted that she had very little urine output. 1. What is happening to Ms. Jones’s kidneys, and why is it causing the observed symptom? Since Ms. Jones just had open-heart surgery to replace the blocked vessels in her heart, her kidneys did not have enough blood flowing to

with a long history of heart failure secondary to a large left ventricular infarct. She had poor activity tolerance and required assistance with activities of daily living. Even minimal activity was associated with moderately severe dyspnea and exertional chest pain, which was relieved by rest. A.O. also exhibited marked pedal edema bilaterally. She took digitalis, furosemide (Lasix), KCl, and sublingual nitroglycerin. Discussion Questions 1.Which type of heart failure (left or right sided) is

Cardiovascular disease also called heart disease includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke (“What is Cardiovascular Disease (Heart Disease)?”). The purpose of this paper

Hypertension and the Renin-Angiotensin-Aldosterone System Renin-Angiotensin-Aldosterone System The renin-angiotensin-aldosterone system, otherwise known as RAAS is a complex hormone system that regulates blood pressure and fluid balance in the human body. When blood volume is low, juxtaglomerular cells in the kidneys activate prorenin, which secretes renin directly into the blood stream circulation. Subsequently, a drop in blood volume additionally releases angiotensinogen from liver, in which
