Question

Quizplus · Accepted Answer

The primary effect of normal age-related changes in the functioning of the heart is slower blood flow throughout the circulatory system, as the heart becomes less efficient at pumping blood. This can result in decreased oxygen delivery to the body's tissues and organs, and can contribute to an increased risk for cardiovascular disease. While there may also be some increase in heart rate during exercise, this is not the primary effect of aging on the heart. Softer, thinner artery walls may be a consequence of aging, but this is not a direct effect on the functioning of the heart.
