ANSWERS WITH COMPLETE SOLUTIONS
What is arteriosclerosis?
Stiffening and hardening of arterial walls.
What is atherosclerosis?
Narrowing of arteries due to plaque buildup.
What is the difference between arteriosclerosis and atherosclerosis?
Atherosclerosis is a subset of arteriosclerosis.
What is PVD?
Peripheral Vascular Disease.
What is a thrombus?
A blood clot that forms within a blood vessel.
What is an embolus?
A blood clot or foreign material that travels through the bloodstream and blocks a blood
vessel.
What is an aneurysm?
A bulge or weakening of a blood vessel wall.
What are the layers of the arterial system?
Intima, media, adventitia.
