That is why, heart may not pump sufficient blood to body. Moreover, during activity heart may not contract properly due to thickened heart walls and can be less responsive to stimulation of nervous system (Young, n.d.). The blood vessels that are the part of our circulatory system also undergo subtle changes during aging process. Changes include loss of elastic property of blood vessels and this could reduce their ability to maintain blood pressure effectively (Young n.d.). According to Jackson & Wenger (2011), “An important concept in the physiology of cardiovascular aging is ventricular-vascular coupling. This theorizes that the increase in vascular and left ventricular stiffness combine to achieve stability in resting cardiac output at advanced age; however, these changes impair the ability of the cardiovascular system to accommodate to stress. That is why, in older adults, cardiac output and index at rest are normal, but do not increase as significantly during exercise and stress as those of the younger patient, due to a variety of factors, including decreased response to autonomic nervous
