What are the tonsils?

Quick Answer

The tonsils are lumps of immune tissue in the throat that help trap germs entering through the mouth and nose.

The Full Story

The tonsils are part of the body’s immune defense at the entrance to the throat. The palatine tonsils are the ones commonly removed in surgery, but there are also lingual and pharyngeal tonsils. They contain immune cells that help recognize and respond to pathogens. While they can help protect against infection, they can also become inflamed, enlarged, or infected, causing sore throat or difficulty swallowing.
