The lymphatic or lymph system involves an extensive network of vessels that pass through almost all our tissues to allow the movement of a fluid called lymph. Lymph fluid circulates through the body in a similar way to blood.
There are about 600 lymph nodes in the body. These nodes swell in response to infection, due to a build-up of lymph fluid, bacteria, or other organisms and immune system cells.
A healthy lymphatic system helps purify the blood through the largest mass of lymph tissue in the body, the spleen. The spleen fights infection and destroys worn-out red blood cells in the body. By cleansing your lymphatic system, your spleen is able to handle these retired red blood cells.
