ANATOMY

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: -Tunica Media It is generally the thickest layer in arteries, and it is much thicker in arteries than it is in veins. The tunica media consists of layers of smooth muscle supported by connective tissue that is primarily made up of elastic fibers, most of which are arranged in circular sheets.

Detailed explanation-3: -Arteries. An artery is a blood vessel that conducts blood away from the heart. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart.

Detailed explanation-4: -Arteries are the largest blood vessels with the thickest walls, and capillaries are the smallest.
