Arteriosclerosis is... A: Hardening of the arteries due to fatty deposits. B: A disease where the blood flow is restricted in the coronary arteries. C: Loss of brain function caused by the interruption in blood flow D: a birth defect where the wall between the left and right side of the heart fails to close causing oxygenated and deoxygenated blood to mix

A stroke is... A: Hardening of the arteries due to fatty deposits. B: A disease where the blood flow is restricted in the coronary arteries. C: Loss of brain function caused by the interruption in blood flow D: a birth defect where the wall between the left and right side of the heart fails to close causing oxygenated and deoxygenated blood to mix

A heart attack is... A: Hardening of the arteries due to fatty deposits. B: A disease where the blood flow is restricted in the coronary arteries. C: Loss of brain function caused by the interruption in blood flow D: when the plaque cracks, it can rupture platelets, which cause the blood to clot. The clot stops the flow of blood causing part of the heart to die.

Valves and heart surgery… There are four valves in your heart: –Aortic valve –Mitral valve –Tricuspid valve –Pulmonary valve The valves control the direction of blood flow through your heart. The opening and closing of the heart valves produce the sound of the heartbeat. Heart valve surgery is open-heart surgery that is done while you are under general anesthesia. A cut is made through the breast bone (sternum). Your blood is routed away from your heart to a heart-lung bypass machine. This machine keeps the blood circulating while your heart is being operated on. Valves may be repaired or replaced. Replacement heart valves are either natural (biologic) or artificial (mechanical): Natural valves are from human donors (cadavers). Modified natural valves come from animal donors. (Porcine valves are from pigs, bovine are from cows.) These are placed in synthetic rings. Artificial valves are made of metal. If you receive an artificial valve, you may need to take lifelong medication to prevent blood clots. Natural valves rarely require lifelong medication.
