Waldeyer's tonsillar ring
(Redirected from Tonsillar ring)
Waldeyer's tonsillar ring (also known as Waldeyer's ring) is a ring-shaped arrangement of lymphoid tissue in the pharynx. Named after the German anatomist Heinrich Wilhelm Gottfried von Waldeyer-Hartz, it is part of the body's immune system and plays a crucial role in the first line of defense against ingested or inhaled foreign pathogens.
Anatomy[edit | edit source]
Waldeyer's ring is located in the nasopharynx and oropharynx at the entrance to the gastrointestinal and respiratory tracts. It includes the adenoid, two tubal tonsils, two palatine tonsils, and the lingual tonsil. These structures work together to protect the body from pathogens entering through the mouth or nose.
Function[edit | edit source]
The primary function of Waldeyer's ring is to provide immune protection. The lymphoid tissues trap incoming pathogens and expose them to white blood cells, which can then destroy the pathogens. This process is particularly important in children, whose immune systems are still developing.
Clinical significance[edit | edit source]
Inflammation or infection of the tonsils within Waldeyer's ring can lead to conditions such as tonsillitis or adenoiditis. In some cases, surgical removal of the tonsils (tonsillectomy) or adenoids (adenoidectomy) may be necessary.
