Question

Quizplus · Accepted Answer

As a person gets older, the fibrous skeleton that supports the heart can become less flexible, which can lead to issues such as reduced ability to pump blood effectively, heart valve problems, and an increased risk of heart failure. Age-related changes may also include smaller coronary vessels, increased pressures in the great vessels, and the development of scar tissue in cardiac muscle. However, maximum cardiac output tends to decrease as a person ages, rather than increase.
