Question 1

In atherosclerosis, the walls of arteries become thicker, stiffer, and can protrude into the lumen. Why would this lead to an increase in blood pressure?

Accepted Answer

A)  The loss of recoil of the arterial wall due to hardening makes it more difficult for the arteries to help blood move downstream away from the heart. 
B)  The artery lumen becomes wider, making it harder for the blood to move away from the heart. 
C)  The hardened artery wall itself requires less blood supply, which increases the amount of blood in the lumen and increases the blood pressure. 
D)  The thickened, hard artery recoils stronger than a normal artery, increasing the blood pressure.
