What effect does age-related thickening of blood vessels have on the body?

Age-related thickening of blood vessels, also known as arteriosclerosis or atherosclerosis, significantly impacts cardiovascular health by reducing the efficiency of blood flow. This thickening causes the blood vessels to become stiffer and narrower, which makes it more challenging for the heart to pump blood. As a result, the overall efficiency of blood flow throughout the body decreases, leading to potential complications such as high blood pressure and reduced delivery of oxygen and nutrients to tissues and organs. Understanding this physiological change is crucial for recognizing the increased health risks associated with aging, which can affect not just circulation but also the body's ability to respond to physical demands efficiently.
