Adenoid Enlargement Anatomy
To better understand enlarged tonsils, it helps to understand the anatomy of the throat and tonsils.
The back of throat is also referred to as the pharynx. More specifically, the pharynx is the back, upper part of the throat behind the tongue. It starts at the base of the tongue and ends at the larynx.
The tonsils and adenoids are paired lymph nodes that are located in the back of the throat. The adenoids are located above the tonsils in the back of the throat. The tonsils and adenoids are part of the immune system, which fights infection.
The tonsils are collections of lymphoid tissue in the back of the throat. They are located on both sides of the throat, near the base of the tongue. The tonsils generally shrink over time. At puberty, the tonsils are normally about the size of an almond.
