Lymph Node
Lymph nodes are small, bean-shaped organs found throughout the body that play an important role in the immune system. They act as filters, trapping foreign particles and pathogens, while also helping to activate the immune system’s response to infections. Lymph nodes are part of the lymphatic system, which helps to maintain fluid balance, transport fat and destroy cancer cells. When there is an infection or disease, lymph nodes can become swollen as they fill with bacteria, viruses, cancer cells, or other foreign particles in order to fight the infection or disease. Swollen lymph nodes can be found throughout the body, but the most common locations include the neck, under the arms, and in the groin.
