Tonsils are part of the lymphatic tissue of the pharynx. There are pharyngeal tonsils, palatine tonsils, pharyngeal tonsils and lingual tonsils, with the palatine tonsils being the largest, which are usually called palatine tonsils.
The pharyngeal tonsils, palatine tonsils, lingual tonsils, tympanic tonsils and lymphatic follicles in the posterior wall of the pharynx and pharyngeal lateral cords together form the endopharyngeal lymphatic ring and participate in the immune function of the body. The endolymphatic ring, which is composed of the human tonsils, is also a terminal immune organ like other immune organs. The tonsils are made up of lymphoid tissue and contain many lymphoid follicles, which contain germinal centers. The lymphatic follicles contain many lymphatic follicles, and the lymphatic follicles contain hair-growing centers, which contain various phagocytes and produce cells and antibodies with natural immunity. The tonsils of children, in particular, have a certain immune function for the organism.
The immune function of children’s tonsils is active, so children’s tonsils are relatively large compared to those of adults. As they get older, after puberty, the immune function of the tonsils gradually decreases and the tonsil tissue gradually shrinks.
