Cardiac Surgery

How the cardiac surgery works, it is helpful to know something about the analysis of the heart. The heart is a muscle containing four chambers that separate oxygen-poor blood from oxygen-rich blood. The atria are the top chambers. They receive blood from the body. The ventricles are the bottom chambers. They pump blood out to the body. Oxygen-poor blood enters the right chamber and then moves through a valve to the right ventricle which is pumped out of the right ventricle to the lungs where it picks up oxygen. The oxygen-rich blood returns to the left atrium of through the pulmonary vein flow through a valve to the left ventricle and is then pumped into the aorta. The blood vessel is the only artery carrying blood out of the heart. Smaller arteries branch off and carry blood to the rest of the body from this very huge, long artery. The first arteries to branch off the blood vessel are the coronary arteries. This carries a continuous supply of oxygen-rich blood to the heart.
