Question

arteries have thick walls whereas as viens have valves

Answer 1

Hey friend here is your answer

Arteries are blood vessels carrying oxygen rich blood from lungs to different parts of the body . Arteries have thick walls so that blood flows with the right pressure

Veins are blood vessels carrying deoxygenated blood from different parts of body for oxygenation. They have to pump blood to different parts so they have valves , this prevents backflow of blood
