Waldeyer's ring is a ring of lymphatic tissue in the throat that helps defend the respiratory and digestive tracts against infections. It is formed by the nasopharyngeal tonsils, palatine tonsils, lingual tonsils, tubal tonsils, and lateral pharyngeal bands. The palatine tonsils are located on either side of the throat and can become infected, causing tonsillitis. Tonsillectomy is the surgical removal of the palatine tonsils, often needed due to issues like recurrent tonsillitis, sleep apnea, or airway obstruction. Waldeyer's ring plays an important role in the body's immune defense as the site of lymphocyte production
