Which statement regarding arteriosclerosis is TRUE? Arteriosclerosis is: a. an acute process of heart muscle degeneration b. thickening and hardening of the vessel wall c. plaque caused by accumlat ... ion of hormones d. fatty streaks and foam cell that are identical.-ANSWERS-thickening and hardening of the vessel wall Arteriosclerosis is a chronic degeneration of blood vessel walls. A plaque is caused by collagen over a fatty streak that is composed of a large number of lipid-laden foam cells that deposit on the vessel wall.
