Lymph nodes and their locations
Lymph Nodes in Your Body~ Lymph nodes are body organs (not glands) spread throughout your body. Their function is to filter out all the dead bacteria, viruses, and other dead tissue from the lymphatic fluid and eliminate it from the body. They are also the place where the white blood cells (lymphocytes) spend much of their time. When the immune system is activated they begin producing large numbers of lymphocytes which causes them to swell.
