Most people are unaware that their lymphatic system pumps lymph throughout their body. It acts as a sewage system, carrying toxins and dead cells out of the body. You actually have three times as much lymphatic fluid in your body as you do blood, about 45 pints of fluid. Unlike the blood, which is moved by the pumping of our heart, lymph fluid is entirely dependent on body movement for circulation.
Your lymphatic system is designed for daily exercise and movement, otherwise it will become stagnant and the toxins will become trapped in your body. The longer these toxins are trapped in your body the more you will be susceptible to infections and disease.
Another function of the lymphatic system is producing antibodies, which fight viruses and bacteria, and destroying abnormal cells, such as cancer cells.
