This magnificent, often mysterious and complex network of vessels, organs and nodes is the body’s cleansing system. It transports excess interstitial fluid out of the tissue and back to the bloodstream. Our cells are located in a sea of lymph, a pale fluid. Oxygen and sugar are transported from the blood vessels to nourish the cells via the lymphatic fluid. Cellular waste, carbon dioxide, lactic acid and metabolites are carried back to the bloodstream through the lymphatic fluid. The lymphatic system is the fluid element of the immune system and directly determines the integrity of the cell.
