lymph node
Body's filtration station
A lymph node is a small, bean-shaped structure in the body's lymphatic system that filters lymph fluid and helps fight infection.
Lymph nodes contain immune cells that trap bacteria, viruses, and other harmful substances.
They cluster in areas like the neck, armpits, and groin, often swelling noticeably during illness: The doctor checked for swollen lymph nodes.
