The palatine tonsils (the tonsils that can be seen when you open your mouth) are the lymphatic tissue of the pharynx and the largest lymphatic tissue in the pharynx (there are also adenoids in the nasopharynx and tonsils at the base of the tongue), which have a defensive role against upper and lower respiratory diseases (with the role of lymphocytes and participate in the immune function of the body), just like the “gatekeeper The role of the tonsils is the same as that of the “gatekeeper” against thieves. However, this role of the tonsils is greater for children and adolescents (during adolescence, the bone marrow is not developed and the body has a high need for lymphocytes, so in order to compensate for the lack of lymphocyte demand, the tonsils develop themselves more vigorously, producing more lymphocytes and entering the body fluids. However, this development of the tonsils is so vigorous that it is easy to form tonsillar hyperplasia and hypertrophy, which is caused by the body’s self-immune regulation function, so this hypertrophy is also called physiological tonsillar hypertrophy, which is not considered a disease by Western medicine, but can cause certain symptoms, such as obstructed swallowing and snoring). Therefore, the tonsils of adolescents can be properly preserved and not easily removed. In adults, since the bone marrow is well developed and no longer needs the tonsils to produce lymphocytes, the tonsils lose their role and value of existence and can therefore be completely removed.
