How does blood at low pressure return to the heart?
After squeezing through capillaries, blood is no longer significantly pressurized by the heart. The pumping action that returns it to the heart is created by a combination of one-way valves in the veins and body movement. The valves prevent blood from flowing backward, and ordinary flexing of muscles and body puts pressure on changing parts of the venuous system. Where there is pressure from the surrounding tissue, veins are squeezed; blood, unable to flow back, flows towards the heart. If you sit without moving for long periods of time, blood will pool in your legs and cause real problems. Fighter pilots with no room to move legs had to wear special suits that would squeeze their legs to pump blood.
