Lymph node Explanation

A lymph node or lymph gland is an ovoid or kidney-shaped organ of the lymphatic system and of the adaptive immune system. These ovoid organs are present throughout the body. They are linked by the lymphatic vessels and they form a part of the circulatory system. Lymph nodes are major sites of B and T lymphocytes, and other white blood cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells. Lymph nodes do not have a detoxification function, which is primarily dealt with by the liver and kidneys.
