(Lymph is pronounced limf.) This network is a part of the bodyâs immune system. It collects fluid, waste material, and other things (like viruses and bacteria) that are in the body tissues, outside the bloodstream. Lymph vessels are a lot like the veins that collect and carry blood through the body.
1. The macrophages and lymphocytes within lymph nodes filter lymph and remove bacteria and cellular debris before lymph is returned to the blood. 2. Lymph nodes are also centers of lymphocyte production; these cells function in immune surveillance.p. 386). A. The hydrostatic pressure of tissue fluid drives the entry of lymph into lymphatic capillaries. B. Forces that move blood in veins (skeletal muscle contraction, breathing movements, and contraction of smooth muscle in the walls of lymphatic trunks) are the forces that propel lymph through lymphatic vessels.
