Veins function to move blood toward the heart, usually carrying blood low in oxygen. Veins have thinner walls with less muscle and a larger lumen in comparison to arteries. Valves are located within veins to prevent back flow. Circulation is mostly due to skeletal muscles contracting, forcing blood upwards, and to pressure changes caused by breathing movements.
