Explanation:
Detailed explanation-1: -Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries. This feature of the elastic arteries allows them to maintain a relatively constant pressure gradient despite the constant pumping action of the heart.
Detailed explanation-2: -Arteries are blood vessels that carry blood away from the heart. Because they are under high pressure, arteries have strong elastic walls. The largest artery from the heart is called the aorta.
Detailed explanation-3: -circulatory system The tunica adventitia, the outermost layer, is the strongest of the three layers. It is composed of collagenous and elastic fibres.
