Explanation:
Detailed explanation-1: -Arteries are blood vessels that carry blood away from the heart to other tissues. The arteries are the first blood vessels that the heart pumps blood through, they experience the highest blood pressure, so they have thick elastic walls to withstand the high pressure.
Detailed explanation-2: -Arteries and arterioles have relatively thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood flow.
