Final answer:
The flow of lymph is indeed maintained by the skeletal muscle pump through muscle contractions.
Explanation:
True, the flow of lymph is maintained by the skeletal muscle pump, which involves the milking action of muscle contractions. Unlike the cardiovascular system, the lymphatic system relies on the peristalsis of lymphatic vessels and the rhythmic contractions of skeletal muscles surrounding the vessels to propel lymph in one direction. Valves in the lymphatic vessels prevent the backward flow of lymph, ensuring its movement towards the heart.
