Explanation:
Detailed explanation-1: -Arteries carry oxygen rich blood from the heart to all parts of the body. Since the heart pumps blood into the arteries the blood flow is always rapid and at high pressure. The arteries have to withstand the high pressure at which heart is pumping blood. Hence they have thick elastic walls.
