WHY LYMPH NODES SWELL IN NECK

The lymphatic system is a network of vessels and nodes that helps fight infection and maintain fluid balance in the body. Lymph nodes are small, bean-shaped structures that are located throughout the body, including the neck. When lymph nodes become swollen, it is usually a sign that the body is fighting an infection.
