Atherosclerosis in artery. Artwork of a longitudinal section through an artery that has been narrowed by atherosclerosis. Narrowing is referred to as stenosis. The flow of red blood cells (erythrocytes) is inhibited at the constricted point. Atherosclerosis is a condition where deposits called atheromas form on the inner walls of blood vessels. Atheromas typically consist of cholesterol, decaying cells, blood cells and fatty proteins. Narrowed blood vessels raises blood pressure, which puts strain on the heart. Atheromas blocking coronary blood vessels cause heart attacks.
