Abstract: . . .  a classmate the different signs and symptoms. 3 Arteriosclerosis n Chronic disease of the arterial system n Characterized by an abnormal thickening and hardening of the vessel walls. Smooth muscle cells and collagen fibers move into the tunica intima causing stiffening Inhibits the arterys ability to change lumen size n Structural changes may be due to the normal aging process Changes in lipid, cholesterol, and phospholipids are contributing factors Page 2 4 Atherosclerosis Plaque Formation n A form of arteriosclerosis in which the hardening of the vessel walls are caused by soft deposits of intrarterial fat and fibrin that harden over time n Damaged endothelium n Fatty streak formation n  . . .
