Explanation:
Detailed explanation-1: -Muscular arteries contain more smooth muscle cells in the tunica media layer than the elastic arteries. Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries.
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.
