Define atherosclerosis and explain why, although it may affect blood vessels throughout the body, it is most serious when it affects coronary or cerebral arteries
What will be an ideal response?
Atherosclerosis is a condition in which blood vessels are narrowed by deposits of plaque in their lining. Atherosclerosis in coronary arteries—the arteries supplying oxygen and nutrients to the heart muscle itself—can so significantly reduce blood flow that an area of the heart muscle experiences severe ischemia and a heart attack occurs. A blockage can also cause a microscopic tear in an artery, and a clot—a thrombus—can form. If the thrombus breaks off from the artery, it can travel as an embolus through the circulatory system until it completely blocks a narrow vessel. This also will result in a heart attack. Atherosclerosis in a cerebral artery can similarly cause ischemia or thrombus formation, causing a cerebrovascular accident, or stroke.
