Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
Arteries transport pure blood from the heart to all parts of the body. But veins transport impure blood from the parts of the body back to the heart and to prevent the back ow of blood, veins have valves.
