Vedclass · Answer

(B) As humans age,the walls of the arteries undergo structural changes,primarily the loss of elastin fibers and the deposition of collagen. This leads to a condition known as arteriosclerosis or hardening of the arteries. Because the arteries become less elastic (stiff),they cannot expand and recoil effectively during the cardiac cycle. Consequently,the heart must exert more force to pump blood through these rigid vessels,leading to increased blood pressure. Therefore,the correct answer is $B$.
