MICROANATOMY

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: -Large arteries, also known as elastic arteries, examples of large arteries include the aorta and the pulmonary arteries. The tunica intima of the large arteries is quite thick with predominant smooth muscle in the subendothelial layer of the tunica intima.

Detailed explanation-3: -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.
