It acts as a filter for harmful substances, such as bacteria and viruses, and helps trap and destroy them. Lymph nodes are connected by a network of vessels called the lymphatic system, which transports a fluid called lymph throughout the body. Inside the lymph nodes, immune cells called lymphocytes are produced and stored, ready to respond to any potential threat. Lymph nodes can become swollen or enlarged when the body is fighting an infection or disease. They also play a critical role in the spread of cancer, as cancer cells can travel through the lymphatic system and get trapped in nearby nodes. Understanding the structure and function of lymph nodes is important in diagnosing and treating a variety of conditions, including infections, autoimmune disorders, and cancer.
