D) decreased calcification of arterial walls.

Question

Quizplus · Accepted Answer

Aging in the cardiovascular system often leads to reduced cardiac output, or the volume of blood that the heart can pump per minute. This is due to a number of factors such as decreased contractility of the heart muscle, stiffening of the heart chambers, and reduced sensitivity to the hormones that regulate heart rate and force contraction. Overall, this can lead to decreased exercise capacity, fatigue, and increased risk of heart failure.
