The narrowing of a vein as a result of plaque build-up is known as atherosclerosis. Atherosclerosis is a type of arteriosclerosis that affects the arteries. The condition disrupts the flow of blood throughout the body, posing serious cardiovascular risks. When the endothelium is damaged, LDL cholesterol accumulates in the arterial wall, causing atherosclerosis. To clean up the cholesterol, the body sends macrophage white platelets. However, the cells can sometimes become stuck at the impacted spot. After a period of time, plaque forms, which is made up of bad cholesterol (LDL cholesterol) and macrophage white platelets. The plaque obstructs the corridor, causing the blood flow around the body to be disrupted.
