These white blood cells, called lymphocytes, fight disease.

Lymph is filtered by the lymph nodes and tonsils. When you have an infection, your lymph nodes or tonsils can become larger. They become filled with a large number of white blood cells that are fighting bacteria or virus causing your infection. The thymus gland helps certain white blood cells to grow. The spleen destroys damaged red blood cells.
