Atherosclerosis, or hardening of the arteries, is a condition in which plaque builds up inside the arteries. Plaque is made of cholesterol, fatty substances, cellular waste products, calcium and fibrin (a clotting material in the blood).
This accumulation of plaque is known as atherosclerosis. Arteries are very flexible and open and close every time the heart beats. They work hard, and the closer they are to the heart, the harder they work and the greater the stress. Over time this mechanical stress can cause lesions to occur within the artery.
