sagittal view of tonsils and throat anatomy. [edit on Wikidata] Tonsils are collections of lymphoid tissue facing into the aerodigestive tract. The set of lymphatic tissue known as Waldeyer’s tonsillar ring includes the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsil.
The palatine tonsils and the adenoid tonsil are organs consisting of lymphoepithelial tissue located near the oropharynx and nasopharynx (parts of the throat). Humans are born with four types of tonsils: the pharyngeal tonsil, two tubal tonsils, two palatine tonsils and the lingual tonsils.
Tonsil Conditions. Acute tonsillitis: A bacteria or virus infects the tonsils, causing swelling and a sore throat. The tonsil may develop a gray or white coating (exudate). Chronic tonsillitis: Persistent infection of the tonsils, sometimes as a result of repeated episodes of acute tonsillitis.
