Lymphatic Circulation
Lymphatic CirculationLymphatic vessels are endothelial tubes within the tissues. They carry fluid, serum proteins, lipids, and foreign substances from the interstitial spaces back to the circulatory system.Lymphatic vessels begin as blind-ended lymphatic bulbs. The wall of a lymph capillary is constructed of endothelial cells that overlap one another. The pressure in the interstitial fluid surrounding the capillary pushes open the overlapping cells of the lymphatic bulbs. The movement of fluid from the surrounding tissue into the lymphatic vessel lumen is passive. That is, there are not active pumps in the lymphatic system. Once the interstitial fluid enters a lymph capillary, it is referred to as lymph.
