The movement of lymph within lymphatic vessels is dependent upon _____.
Skeletal muscle contraction, peristalsis of muscles around lymphatic vessels and the action of one-way valves.
Unlike the circulatory system, that has the heart to pump blood through the system, the lymphatic system does not have a pump. The Lymph is moved through the lymphatic vessels by contractions of the lymphatic vessels and the movement of the surrounding digestive system and skeletal muscles. Also the one-way action of valves within the lymphatic capillaries, help in its motion or circulation.
