The tonsils, which can be divided into pharyngeal tonsils, pharyngeal tonsils, palatine tonsils, and lingual tonsils, are located in the upper back of the pharynx, on both sides of the pharynx, in the tonsillar fossa on the side wall of the pharynx, and in the lower part of the pharynx, respectively. The palatine tonsils are the largest and are commonly referred to as the palatine tonsils, which belong to the oropharynx and are lymphoepithelial organs with a defensive function. They are located in the tonsillar fossa on the lateral wall of the oropharynx and are elliptical in shape, with the inner side facing the pharyngeal cavity, covered with mucous membranes, and with deep tonsillar fossae. The palatine tonsils, together with the pharyngeal tonsils above the pharynx, the pharyngeal tonsils on both sides, and the lingual tonsils below, form the pharyngeal lymphatic ring, which has a defense function against the digestive and respiratory tracts. This area is susceptible to bacterial attack, if you have tonsil redness, swelling, pain and discomfort, it is recommended to go to the hospital to avoid delays in the condition.
