In the cardiovascular system, aging is associated with a decrease in which two aspects?

• A. Increase
• B. Decrease
• C. Fluctuate
• D. No change

Answer: (B)

Aging tends to reduce several aspects of cardiovascular performance rather than increase them. Two common declines are the heart’s ability to ramp up its rate and output during activity (the chronotropic response and stroke‑volume reserve) and the elasticity of the arterial system (arterial compliance), which tends to stiffen with age. Because these key functions typically diminish as people get older, the overall trend is a decrease. This is why the option describing a decrease best fits aging in the cardiovascular system. Increased, fluctuating, or no change are not the typical patterns observed with aging in this context.
