Answer to Question 1
Plaque deposits are made from fats, cholesterol, and other substances, which accumulate over time thickening and weakening artery walls. The plaques develop within rather than on the artery wall and are driven by an inflammatory process. The plaque reduces the size of the lumen, resulting in a decreased amount of blood flow to the tissues. The reduced flow prevents an adequate supply of nutrients and oxygen from reaching the tissues.
