The lymphatic system has three functions: 1. Fluid Recovery; 2. Immunity, and; 3. Lipid absorption. It is the body’s internal drainage system which is designed to rid your blood of acidic and toxic waste (the lymph system filters these toxins into our body’s major detox organs, the liver and kidneys). The tonsils, adenoids, spleen, and thymus are all part of the lymphatic system, all connected by a web of lymphatic vessels which, in a sense, is like a second circulatory system of the body.
