Arteries carry blood from the heart to various organs of the body under high pressure so they have thick and elastic walls. Veins collect the blood from different organs and bring it back to the heart. The blood is no longer under pressure so, the walls are thin with valves to ensure that blood flows only in one direction.

Answer:
Veins are thin walled as they more superficial that is they are located closer to the skin and they have valves in their inner lining to prevent the backflow of blood.
