what is the interstitial fluid collected by structures of the lymphatic system
The lymphatic system reabsorbs interstitial fluid so that the body does not lose liquid with every pump of the heart. Once it enters the lymphatic system, interstitial fluid is called lymph. Lymph contains fat from circulating through the small intestine as well as numerous waste products from bodily cells. The waste is slowly filtered out by a series of small bean-shaped organs called lymph nodes.
