Which has thicker vessel walls?

Arteries carry blood away from the heart and veins return blood to the heart. Veins are generally larger in diameter, carry more blood volume and have thinner walls in proportion to their lumen. Arteries are smaller, have thicker walls in proportion to their lumen and carry blood under higher pressure than veins.
