Veins carry blood away from the tissues and towards the heart. They have thin walls, a larger lumen than the arteries and usually have valves to prevent a retrograde direction of transport. Blood that returns to the heart via the veins comes from the capillaries, where the arterioles and venules meet and the exchange of gases, nutrients and waste products takes place.
