Question

Explain what plaque is (plaque from arteries) and why it is harmful to one's health.

Answer 1

Plaque itself can pose a risk. A piece of plaque can break off and be carried by the bloodstream until it gets stuck. And plaque that narrows an artery may lead to a blood clot (thrombus) that sticks to the blood vessel's inner wall. In either case, the artery can be blocked, cutting off blood flow.

Answer 2

Plaque is made up of deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin. As it builds up in the arteries, the artery walls become thickened and stiff. Atherosclerosis is a slow, progressive disease that may start as early as childhood. However, it can progress rapidly. Coronary artery disease starts when fats, cholesterols and other substances collect on the inner walls of the heart arteries. This condition is called atherosclerosis. The buildup is called plaque. Plaque can cause the arteries to narrow, blocking blood flow.
