Waldeyer's ring is a ring of lymphoid tissue surrounding the pharynx that guards the airway and digestive tract, with components in the nasopharynx and oropharynx. At the oropharyngeal level, the primary tonsils are the palatine tonsils. They sit in the tonsillar fossae on either side of the isthmus of the fauces, between the palatoglossal and palatopharyngeal arches, placing them squarely in the oropharynx and making them the classic tonsillar component of the ring. Lingual tonsils are at the base of the tongue (also part of Waldeyer's ring) but are located more posteriorly, while pharyngeal (adenoids) and tubal tonsils are in the nasopharynx vicinity.
