About Lymphatic System
The lymphatic system returns excess tissue fluid to the bloodstream and supports immune defence through lymph, lymph vessels, lymph nodes, the spleen, thymus and tonsils. It also transports absorbed fats from intestinal lacteals, which distinguishes lymphatic circulation from the blood vascular system.
