The lymphatic system is one of the more complex systems of the body. It is responsible for keeping a person's fluids balanced and putting fluids into the blood. It is also responsible for making leukocytes and antibodies to help fight infection and disease. A chart of how the lymphatic system works would show you all the capillaries, vessels and nodes that make up the system. Some charts will even show you in detail how things flow in and out of each node and filter out through the body.
