Final answer:
True. Skeletal muscle contraction aids in pumping blood through veins by increasing the pressure and forcing blood closer to the heart.
Step-by-step explanation:
True. The skeletal muscle contraction aids in pumping blood through veins. This mechanism is known as the skeletal muscle pump. When the surrounding skeletal muscles contract, they compress the blood and increase the pressure in that area. As a result, blood is forced closer to the heart where the venous pressure is lower, helping to move the blood back to the heart. The one-way valves in the veins ensure that blood flows only in the proper direction.
