Blood in arteries moves because of 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.
Blood flows away from the heart and is measured as blood pressure. This is a measure of the passage or flow and the resistance of the flow in the arteries.
