Waldeyer's ring

Waldeyer's ring is a circular arrangement of lymphoid tissue located in the throat and mouth area. It includes structures such as the tonsils and other lymph nodes that help the immune system identify and fight infections entering through the mouth or nose. This ring acts as a frontline defense, monitoring pathogens and initiating immune responses to protect the body from illnesses that can enter through these routes. It plays an important role in oral and respiratory immune health by filtering out harmful microbes early in the infection process.
