What processes mechanisms assist blood flow in returning from the lower extremities?

Mechanisms to Return Blood The return of blood to the heart is assisted by the action of the skeletal-muscle pump and by the thoracic pump action of breathing during respiration. As muscles move, they squeeze the veins that run through them. Veins contain a series of one-way valves.
