lymphatic system
(lim-FAT-ik) The network of small vessels and tissue spaces that move lymph throughout the body. The lymphatic system has several functions, including filtering out harmful bacteria; manufacturing white blood cells (white blood cells are produced by the lymph nodes); distributing nutrients to the cells of the body; helping to maintain the bodys fluid balance by draining off excess fluids so that tissues do not swell; and assisting in the digestion of fats.
