The valves in the veins
It's responsible for the beating of the heart and closing of valves in the veins of the legs.

The muscles in your legs help transport blood back to your heart. The veins in your legs also have valves to help this process and prevent blood from flowing back down towards your feet.
One-way valves prevent the back flow of bloodThere are tiny one way valves throughout a vein. These stop blood from flowing backwards. Interestingly, when these valves in veins in the legs malfunction, the result are varicose veins.
Muscular contraction in the extremities moves the blood through the veins, the valves only allow blood to move toward the heart.
To prevent back flow of blood as the blood pressure in veins is greatly decreased compared to artieries
In order to pump the blood back up the legs to the body and heart, there are small, one-way "flapper" valves in the veins that prevent the blood from flowing backwards back down into the legs. These valves help reduce the pressure in the veins and allow the movement of the muscles in the legs to help squeeze the blood upwards. Without the valves, this squeezing is more likely to push the blood down instead of up.
If they are big and kind of stick out a little, they might be varicose veins. Lower extremity veins normally have valves in them to help pump blood from the legs back to the heart. In varicose veins, these valves have stopped working. Varicose veins can be potentially dangerous and can lead to blood clots. I'm pretty sure surgery is the only fix.
