A Lymph node (IPA: [ lɪmf noʊd]) is an organ consisting of many types of cells, and is a part of the lymphatic system. Lymph nodes are found all through the body, and remove foreign (not of the body) objects from the body. Lymph nodes contain white blood cells. They are important for the correct use of the immune system.[1]
