Which statement about Waldeyer's ring is true?

The concept here is the arrangement and components of Waldeyer's ring, the circular collection of lymphoid tissue at the entrance to the respiratory and digestive tracts that helps sample pathogens. It is formed by three major tonsillar groups: the palatine tonsils located in the oropharynx between the palatoglossal and palatopharyngeal arches, the pharyngeal tonsil (adenoids) on the roof of the nasopharynx, and the lingual tonsils at the base of the tongue. This trio creates the ring that guards the airway and initiates immune responses to inhaled or ingested antigens. Some sources also mention tubal tonsils near the Eustachian tube openings, but the classic components are these three. So the inclusion of the palatine tonsils, pharyngeal tonsil, and lingual tonsils accurately describes Waldeyer's ring.
