There are also one way valves in the circulatory system.
in the arterial system, your heart keeps pushing everything forward.

Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
These are valves, and are found in veins to prevent blood from flowing backwards.
