Your muscles need protein, nutrients, and oxygen to move and work. Then the circulatory system carries thos...

Coronary Artery Disease High Blood Pressure
2,644 wordsAneurysm-This term refers to a localized dilation of an artery or chamber of the heart. The behavior and prognosis for aneurysms varies, depending on their size and location. Aneurysms of the heart are usually the result of a prior heart attack. They generally don't require surgical resection. They may result in congestive heart failure and arrhythmias. Aneurysms of the main artery of the body, the aorta, generally require resection once they reach a certain size-anywhere from 4. 5 to 6. 0 centi...

When the right ventricle beats or contracts, the blood flows through the pulmonary valve and into the lungs where it becomes oxygenated. The oxygenated blood returns to the heart, pooling in the left atrium. The mitral valve allows the blood to pass from the left atrium to the left ventricle. When the left ventricle contracts the blood travels through the aortic valve into the aortic arch for distribution throughout the body. (Cardiac, Hea...

Divided Into Four Pulmonary Artery
3,525 wordsTheHheart Biology Histology The Human Heart. Abstract: Dorlands Illustrated Medical Dictionary defines the heart as the viscus of cardiac muscle that maintains the circulation of the blood. It is divided into four cavities; two atria and two ventricles. The left atrium receives oxygenated blood from the lungs. From there the blood passes to the left ventricle, which forces it via the aorta, through the arteries to supply the tissues of the body. The right atrium receives the blood after it has p...
