Final answer:
Atherosclerosis is arteritis of the aorta and aortic branches resulting in stenosis/occlusion/aneurysms. It is a specific type of arteriosclerosis, which is the more generalized loss of compliance or 'hardening of the arteries'.
Step-by-step explanation:
Atherosclerosis is arteritis of the aorta and aortic branches resulting in stenosis/occlusion/aneurysms. It is a condition in which plaque builds up inside arteries, causing narrowing of the lumen and stiffening of the arterial walls. Atherosclerosis is a specific type of arteriosclerosis, which is the more generalized loss of compliance or 'hardening of the arteries'.
