👉 The term "nasopharyngeal" refers to the part of the body that is located between the nose and mouth, usually on the left side. It includes the area around the nostrils, which are responsible for breathing air into the lungs and exhaling it out through the mouth. The nasopharynx also contains a number of structures, including the pharynx (throat), larynx (voice box), and tonsil (tonsillar masses).
