atherosclerosis vs. arteriosclerosis: What’s the difference?

Arteriosclerosis is a condition involving the thickening and hardening of artery walls resulting in lessened blood flow. Atherosclerosis is a common type of arteriosclerosis in which fatty substances form deposits on artery walls. Sclerosis is a general term for hardening of tissue. Arterio- means “artery”; athero- refers to the fatty deposits found in atherosclerosis and other conditions.
