What causes blood to move through veins?

Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.

What causes blood to flow in veins?

When your muscles contract, the valves open, and blood moves through the veins. When your muscles relax, the valves close, keeping blood flowing in one direction through the veins. If the valves inside your veins become damaged, the valves may not close completely. This allows blood to flow in both directions.
