Lymph nodes are part of the lymph system, which carries lymph
fluid, nutrients, and waste material between the body tissues and the
bloodstream. The three most common sites of swollen lymph nodes are the neck, armpit, and groin. The lymph system is also an important part of the immune
system, the body's defense system against disease.
