(Lymph is pronounced limf.) This network is a part of the bodyâs immune system. It collects fluid, waste material, and other things (like viruses and bacteria) that are in the body tissues, outside the bloodstream. Lymph vessels are a lot like the veins that collect and carry blood through 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.
