Function of Lymph Nodes

The lymph nodes are small, cellular structures found almost all over the body. There are between 600-700 lymph nodes in the entire body. The lymph nodes belong to the lymphatic system in the human body. The lymphatic system's role is to get rid of any toxins and waste products that may accumulate. The lymphatic system has lymph fluid that travels around the body and is connected to lymph nodes where the bacteria and other waste products are filtered out of the lymph fluid. Lymph nodes containinfection-fighting elements. Commonly-known examples of lymph nodes in the body are the spleen, tonsils and adenoids.

Function of Lymph Nodes

An individual lymph node resembles a bean and is encapsulated by connective tissue. On the inside, there are various sections called nodules. It is here that the lymphocytes are stored. Other components of the immune system, like macrophages, are stored in the medulla, which are at the center of the lymph node. Lymphatic vessels enter and leave the lymph gland carrying lymph fluid.
