● The pharynx (FAIR-inks) is the common posterior space for the respiratory and digestive
systems
● (1) Nasopharynx
● That portion of the pharynx specifically related to the respiratory system is the
nasopharynx
● It is the portion of the pharynx above the soft palate
● The two posterior openings (nares) of the nasal chambers lead into the single space of
the nasopharynx
● The auditory (eustachian) tubes also open into the nasopharynx
● The auditory tubes connect the nasopharynx with the middle ears
● This will equalize the pressure between the outside and inside of the eardrum
● Lying in the upper posterior wall of the nasopharynx are the pharyngeal tonsils
(adenoids)
● The soft palate floor of the nasopharynx is a trapdoor which closes off the upper
respiratory passageways during swallowing
