Answer:
Veins have thin walls because the blood there is no longer under pressure and they have valves to ensure blood flow in one direction.
Veins collect the blood from different organs and brings it back to heart. The blood is no longer under so the walls are thin with valves to ensure that blood flows only in one direction.
