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.
