Explanation:
Detailed explanation-1: -Large arteries receive the highest pressure of blood flow and are thicker and more elastic to accommodate the high pressures. Smaller arteries, such as arterioles, have more smooth muscle, which contracts or relaxes to regulate blood flow to specific portions of the body.
Detailed explanation-2: -Blood pressure is the amount of force exerted on the artery walls by the pumping blood. High blood pressure (hypertension) means that your blood is pumping with more force than normal through your arteries. The added stress on the arteries can speed up the clogging of arteries with fatty plaques (atherosclerosis).
