The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat (pharynx).
Tonsils and adenoids are the body’s first line of defense as part of the immune system. They sample bacteria and viruses that enter the body through the mouth or nose, but they sometimes become infected.
