The lymphatic system is a nexus, or series, of vessels similar to that of the circulatory system—the branching vessels move vital bodily fluid throughout the tissues and organs of the body.

The lymphatic system is a network of tissues and organs that runs throughout the body. Primarily consists of lymph vessels, lymph nodes and lymph. The tonsils, adenoids, spleen and thymus are all part of the lymphatic system. The lymphatic system is like the blood circulation - the tubes (vessels) branch through all parts of the body like the arteries and veins that carry blood.
