Explanation:
Detailed explanation-1: -Veins have valves to prevent this backflow of blood. Valves ensure that blood flows only in one direction through veins. Therefore, veins have valves, not the arteries.
Detailed explanation-2: -Veins and arteries share this general structure. However, veins are different from arteries because they sometimes also contain one-way valves that keep blood flowing in the right direction. These valves are especially important in your legs, where they help blood move up toward your heart.
