Solution

Blood in arteries moves because of the pressure of blood from the heart. Each time the heart pumps, it pushes the blood a little further. Veins do not rely on the heart to move blood. Veins have a system of valves to keep the blood from not moving backwards, and muscles contract the veins to move the blood.
