What is Waldeyer's ring?

 Waldeyer’s ring is a complete ring of subepithelial lymphoid tissue present in and comprising of palatine tonsils, adenoids, lingual tonsils, tubal tonsils and the pharynx.

2) Nasopharyngeal tonsil (adenoids)
3) Lingual tonsil present on the posterior 1/3 of tongue
4) Tubal tonsil near the Rosenmuller’s fossa
5) Lateral pharyngeal bands

What is the importance of Waldeyer’s Ring ?
1) It is an important part of mucosal associated lymphoid tissue (MALT) which processes antigen and presents it to T-helper cells and B-cells.
2) This ring acts as a protective barrier for the lower respiratory tract
3) Waldeyer’s ring occupies the entry of air and food passage and is constantly exposed to new antigenic stimuli.
4) Production of immunoglobulins : The tonsillar tissue produces IgG, IgA and IgD. These immunoglobulins are secreted into pharynx and their output is increased in response to a wide variety of inflammatory processes.
5) The tissue of Waldeyer’s ring undergoes physiological hypertrophy during early childhood as the child is exposed to increasing amount of antigenic stimuli.
Regression : This lymphoid tissue reaches its maximum size by 10 years of age and then gradually regresses.
