Hardening of the arteries due to cholesterol plaques is called atherosclerosis or arteriosclerosis. The term Atherosclerosis literally means hardening from atheroma. In a heâ¦althy person, the artiers have walls that are muscular, smooth and elastic enough to allow for variations in blood pressure, which allows the blood to pass through freely.
Cholesterol is a type of fat (lipid) in your blood. Your cells need cholesterol, and your body makes all it needs. But you also get cholesterol from the food you eat. If you have too much cholesterol, it starts to build up in your arteries. (Arteries are the blood vessels that carry blood away from the heart .) This is called hardening of the arteries, or atherosclerosis. It is the starting point for some heart and blood flow problems.
