Consisting of lymph, lymph nodes, lymphatic vessels and capillaries, this additional circulatory system helps the veins to remove waste from intercellular fluids. It circulates lymph through vessels and nodes and carries lymphocytes (white blood cells) as part of the body's defence system.

The circulation and pumping process of the lymphatic system is stimulated only by direct muscle movement. Chi Gung works extensively on the body's muscle and soft tissue allowing fine muscular contraction which stimulates and massages the lymphatic nodes, maximizing the transportation of lymph throughout the body and bolstering immune responses.
