• Cholesterol is a waxy, fat-like substance made in the liver and found in certain foods, such as dairy products, eggs, and meat.
  • The body needs a small amount of cholesterol in order to function properly. Its cell walls, or membranes, need cholesterol in order to produce hormones, vitamin D, and the bile acids that help to digest fat.
  • Coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle. The coronary arteries can get blocked by the buildup of plaque. Plaque is made up of extra cholesterol, calcium, and other substances that float in blood. Over time, plaque can build up on the inside walls of the coronary arteries and block the blood flow and contribute to atherosclerosis (hardening of the arteries) which can lead to heart disease.
