Tonsils and Adenoids

Tonsils are almond-sized structures located at the back of the throat. Adenoids (pharyngealtonsils) are embedded in the upper rear wall of the oral cavity. The adenoids are often important in childhood but usually diminish in size in the progress of  adulthood. All of these tonsillar structures are part of the lymphatic system and contain lymphoid tissue. The function of the tonsils are to process lymphatic fluid and to help in the resistance to bacterial infection.
