Detailed explanation-1: -All arteries have a pulse, but it is most easily felt at points where the vessel approaches the surface of the body.
Detailed explanation-2: -Arteries experience a pressure wave as blood is pumped from the heart. This can be felt as a “pulse.” Because of this pressure the walls of arteries are much thicker than those of veins. In addition, the tunica media is much thicker in arteries than in veins.
Detailed explanation-3: -Overview. Arteries carry oxygenated blood away from the heart to the tissues of the body. Veins carry blood depleted of oxygen from the same tissues back to the heart. The arteries are the vessels with the “pulse, ‘’ a rhythmic pushing of the blood in the heart followed by a refilling of the heart chamber.
