- The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque.
- The build-up of lipids and fibrous components in the major arteries is a hallmark of the degenerative illness known as atherosclerosis. A picture of a typical artery's anatomy can be found in Foam cells, or subendothelial accumulations of cholesterol-engorged macrophages, are the earliest lesions of atherosclerosis.
- Nitric oxide and prostacyclin are two chemicals that are produced by your endothelium. These maintain the fluid in your blood and stop it from clotting when it shouldn't. These compounds' insufficient production is a symptom of various diseases, which raises your risk of clotting.
