Lymph nodes are small rounded or bean-shaped masses of lymphatic tissue surrounded by a capsule of connective tissue. You have some 600 of them throughout your body, with the majority in your head and neck. When they work right, they clean out your system, protecting you from infections and helping your body launch immune responses to foreign substances.
