Answer:

  • The valves close when blood starts to flow in one direction, so that blood in the veins can only flow in the direction back to the heart, which is up the legs. When you squeeze your leg muscles to walk, stand, kick, and move about, the muscles squeeze the veins and force the blood to get moving.
