It is divided into the nasopharynx, oropharynx, and hypopharynx and it communicates with the posterior nares, Eustachian tube, the mouth, larynx, and oesophagus. The pharynx acts as a passage-way for food from the mouth to the oesophagus, and as an air passage from the nasal cavity and mouth to the larynx. It also acts as a resonating chamber for the sounds produced in the larynx.
