lymph node

[limf node] a small, bean-shaped collection of immune system tissue, such as lymphocytes, found throughout the body along lymphatic vessels. They remove cell waste, germs, and other harmful substances from lymph. Cancers often spread to nearby lymph nodes before reaching other parts of the body. Sometimes called “lymph glands.” See also immune system, lymph, lymphatic system.
