Explanation:
Detailed explanation-1: -Arteries have thick walls because they need to withstand high pressure generated by the heart. Veins have thin walls because they do not need to withstand as much pressure. Arteries are also narrower than veins, which allows for faster blood flow.
Detailed explanation-2: -Since the blood pumped from the heart into the arteries flows at higher pressure than the blood in veins, hence arteries need to have thicker walls or else the high blood pressure might cause them to burst.
Detailed explanation-3: -The largest artery in the body is Aorta that pumps oxygenated blood into the body.
