Venous return is the flow of blood back to the heart. This process is achieved by five mechanisms. The Pressure Gradient, now this mechanisms work via the heart generating pressure even though the pressure is weaker in the veins than in the arteries it is still the most important force in the venous flow. Gravity, but only when you are sitting or standing anywhere above the heart simple gravity is at work in returning blood back to the heart, not to say that very thing isn’t still working because it is, it’s more like coasting downhill in your car the car is still running its just using less drive force. The skeletal muscle pump, in the limbs there is contracting by the muscles, which squeezes the blood out of the compressed veins that are
