What are Lymph Nodes?

Lymph nodes, sometimes referred to as lymph glands, are small masses of lymphatic tissues, either rounded or bean-shaped, and encapsulated with connective tissues. Their primary function is to filter the lymphatic fluid and store cells that trap cancer cells or bacteria traveling through the body in the lymph fluid. The lymph nodes are located in a number of locations throughout the body, in the lymphatic system. They are essential to the body’s immune system, and they are the main sites in which many immune reactions begin. They often put out signals, when the body is suffering from infections or cancer, such as swelling, firmness, or becoming fixated in position and are often checked during health examinations for these signs. The most commonly swollen lymph nodes are under the chin, and often the same glands that mothers used to check when children stay home from school with a sore throat.
