The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
Lymphatic vessels contain one-way valves to prevent the back flow of lymphatic fluid. The lymph capillaries drain the lymph to larger contractile lymphatics, which have valves as well as smooth muscle walls. These are called the collecting lymphatics. It is interesting to know that unlike blood circulatory system, your lymphatic system does not possess any pumping organ for the movement of lymph through its network of channels. Tiny one way valves push the lymph from node to node.
