A lymph node is a small, bean-shaped structure that is part of the lymphatic system.
These nodes are distributed throughout the body and act as filters to trap bacteria, viruses, and other foreign substances circulating in the lymph.
They are like control stations that help the immune system fight infections and diseases. When there is an infection or inflammation near a lymph node, it can swell and become sensitive to the touch.
Lymph nodes are an important part of the body’s response to illness and serve a protective function.
