the heart and the veins
The valves keep blood flowing in one direction. And there are even valves in the veins. The system is called a circulatory system and the system must keep going in a circle to function properly.
Circulatory system are connected by a network of arteries, veins and capillaries. They connect the body with heart. Inside the heart, various valves connect different chambers.
if the valves failed then the blood would go in the wrong direction.
