Lymphatic throat ring

The lymphatic throat ring or Waldeyer throat ring is a group of lymphoepithelial tissue that is located in mammals at the transition from the oral cavity and nose to the throat and the deeper airways. The term “ring” is only to be understood in a figurative sense, as it concerns individual tissue islands, the tonsils . The lymphatic ring of the pharynx serves primarily as a defense barrier for the upper respiratory tract against possible invasion of bacteria , viruses and fungi from the oral and nasal cavities.

The Waldeyer throat ring consists of:

• Pharyngeal tonsil (pharyngeal tonsil )
• Tonsilla tubaria (tube almond)
• Tonsilla palatina (palatine tonsil )
• Tonsilla lingualis (tongue tonsil )
• Tonsilla veli palatini (soft palate almond, not in humans)
• Tonsilla paraepiglottica (epiglottis almond , not in humans)
• Lymph follicles in the back wall of the throat

This pharynx ring was named after the German anatomist Heinrich Wilhelm Waldeyer (1836–1921), who first described it.
