the inside of blood vessels. It affects only the inner lining of an artery. It is
characterized by plaque deposits that block the flow of blood.
The plaque formation stimulates the cells of the artery wall to produce substances that accumulate in the inner layer. The artery's diameter is reduced, and blood flow and oxygen delivery are decreased.
