Final answer:
An adenoidectomy is a surgical procedure in which the pharyngeal tonsils, or adenoids, are removed. These are located in the nasopharynx and are often taken out due to obstruction or recurrent infections.
Step-by-step explanation:
The tonsils that are removed during a procedure called adenoidectomy are the pharyngeal tonsils, also known as the adenoids. These are located at the top of the nasopharynx, the area of the throat at the back of the nasal cavity.
Tonsils serve the function of trapping and destroying pathogens to help the body develop immunity. Adenoidectomy is often performed when enlarged pharyngeal tonsils obstruct breathing or cause recurrent throat infections. After tonsil removal, individuals may sometimes ask themselves, "Do you still have your tonsils?" considering their role in fighting germs. Despite their importance in immunity, sometimes enlarged tonsils cause more harm than good, leading to the decision to have them removed.
The locations of the tonsils include the pharyngeal tonsils at the back of the nasal cavity, palatine tonsils at the back of the mouth, and lingual tonsils below the tongue. During adenoidectomy, only the pharyngeal tonsils are removed.
