E) any of these can occur with aging

Question

Quizplus · Accepted Answer

All of these changes can occur with aging and contribute to increased risks of heart disease, stroke, and other cardiovascular disorders. The decreased elasticity of arteries and veins leads to higher blood pressure and reduced blood flow, while the walls of arteries becoming less tolerant of sudden increases in pressure can lead to ruptures and other damage. Events leading to an aneurysm may also occur, where weakened areas of blood vessels balloon out and are at risk of bursting. Finally, calcium salts depositing onto weakened vascular walls can contribute to arteriosclerosis and blockages that can cause heart attacks or stroke.
