The Lymphatic System



The network of lymphatic vessels drains the interstial tissue by returning fluid and particulates to the central veins. Under normal circumstances this is considered an active process, resulting in negative interstitial pressures. The active process is attributed primarily to contractile lymphangions, numerous tiny valved pumps, able to move fluid against a pressure gradient. The possibility that capillary lymphatics have the same ability without the benefit of valves.
