The term 'kind of node or gland' can be answered with the word 'LYMPH, ' which is a type of bodily fluid found in the lymphatic system. LYMPH is composed of white blood cells, proteins, and other substances that help to fight infection and disease. It is also responsible for transporting nutrients and waste throughout the body. LYMPH nodes are small, bean-shaped organs located throughout the body that filter out bacteria and other foreign particles from the LYMPH. Glands, such as the thymus, spleen, and tonsils, are also part of the lymphatic system and help to produce and store lymphocytes, which are white blood cells that fight infection.
