Small, rounded structures along the small vessels of the lymphatic system that are part of the immune system.

Lymph nodes are tiny spherical structures the size of a pin head in groups into which the lymphatic vessels drain through afferent vessels. The nodes filter the lymph, storing and destroying microorganisms by the production of lymphocytes. Once filtered the lymph leaves the node through the efferent lymph vessel.

Popliteal, inguinal, iliac, abdominal, axillary, cubital and cervical are examples of groups of lymph nodes.

Small, compact structures lying along the channels that carry lymph, a yellowish fluid. Lymph nodes produce white blood cells (lymphocytes), which are important in forming antibodies that fight disease.
