TERM: Adenoids and Tonsils

Adenoids and Tonsils: These structures (adenoids and tonsils) in the back of the throat are composed of tissue similar to lymph nodes or "glands."

The tonsils [бүйлсэн булчирхай] are areas of lymphoid tissue on either side of the throat. An infection of the tonsils is called tonsillitis. Most commonly, the term "tonsils" refers to the palatine tonsils that can be seen in the back of the throat. Like other organs of the lymphatic system, the tonsils act as part of the immune system to help protect against infection. In particular, they are believed to be involved in helping fight off pharyngeal and upper respiratory tract infections.

Adenoids [хамар залгиурын булчирхай томролт] (also called pharyngeal tonsils, or nasopharyngeal tonsils) are tissues at the very back of the nose, in the roof of the nasopharynx [хамар залгиур], where the nose blends into the mouth. Normally, in children, they make a soft mound in the roof and posterior wall of the nasopharynx, just above and behind the uvula [хүүхэн хэл]. Taking away adenoids with surgery is called adenoidectomy [хамар залгиурын булчирхай авах].
