The tonsils are a set of lymphoid organs facing into the aerodigestive tract, which is known as Waldeyer's tonsillar ring and consists of the adenoid tonsil (or pharyngeal tonsil), two tubal tonsils, two palatine tonsils, and the lingual tonsils. These organs play an important role in the immune system. When used unqualified, the term most ...
Tonsillitis is inflammation of the tonsils in the upper part of the throat. It can be acute or chronic. [8][9][2] Acute tonsillitis typically has a rapid onset. [10] Symptoms may include sore throat, fever, enlargement of the tonsils, trouble swallowing, and enlarged lymph nodes around the neck. [1][2] Complications include peritonsillar ...
The palatine tonsils with the soft palate, uvula, and tongue visible. Palatine tonsils, commonly called the tonsils and occasionally called the faucial tonsils, [2] are tonsils located on the left and right sides at the back of the throat, which can often be seen as flesh-colored, pinkish lumps. Tonsils only present as "white lumps" if they are ...
Tonsillar crypts. Low-power microscope magnification of a cross-section through one of the tonsillar crypts (running diagonally) as it opens onto the surface of the throat (at the top). Stratified epithelium (e) covers the throat's surface and continues as a lining of the crypt. Beneath the surface are numerous nodules (f) of lymphoid tissue.
The adenoid is a mass of lymphoid tissue located behind the nasal cavity, in the roof and the posterior wall of the nasopharynx, [1] where the nose blends into the throat. The adenoid, unlike the palatine tonsils, has pseudostratified epithelium. [3] The adenoids are part of the so-called Waldeyer ring of lymphoid tissue which also includes the ...

The lingual tonsils are a collection of lymphatic tissue located in the lamina propria of the root of the tongue. [1] This lymphatic tissue consists of the lymphatic nodules rich in cells of the immune system (immunocytes). [2] The immunocytes initiate the immune response when the lingual tonsils get in contact with invading microorganisms ...
Structure. Each tubal tonsil is located posterior to the opening of the Eustachian tube on the lateral wall of the nasopharynx. [1] It is one of the four main tonsil groups forming Waldeyer's tonsillar ring. [2] This ring also includes the palatine tonsils, the lingual tonsils, and the adenoid. [2]
