Describe the major changes that take place in the cardiovascular system with aging.
What will be an ideal response?
Answers will vary. Feedback: The heart becomes less efficient, pumping less forcefully and less blood with each beat, while the number of beats per minute increases. The heart has less ability to gear up for action when the body is under stress. Various parts of the heart and the blood vessels lose elasticity, and fatty substances may be deposited on the inner layers of arteries. These deposits give more resistance to the heart's pumping action, so hypertension may develop. There is less blood flow to all parts of the body.
