The answer is that healthy legs have veins with smooth, elastic walls that are perfectly designed to adapt to the changes in pressure within a vein. Veins have valves that keep blood moving in one direction: back toward the heart. As the leg muscles are activated, the venous valves open to allow one-way flow in the direction of the heart.
