Waldeyer's tonsillar ring is a ringed arrangement of lymphoid tissue in the pharynx. It is named after the German anatomist Heinrich Wilhelm Gottfried von Waldeyer-Hartz, who first described it. This ring of lymphoid tissue plays a crucial role in the immune response by acting as the first line of defense against ingested or inhaled pathogens.

Anatomy[edit | edit source]

Waldeyer's tonsillar ring is composed of several groups of tonsils:

These tonsils are part of the mucosa-associated lymphoid tissue (MALT) and are involved in the production of lymphocytes and antibodies.

Function[edit | edit source]

The primary function of Waldeyer's tonsillar ring is to protect the body from infection. The tonsils contain lymphoid follicles that produce B cells and T cells, which are essential components of the adaptive immune system.

Clinical Significance[edit | edit source]

Waldeyer's tonsillar ring can be involved in various clinical conditions, including:
