The openings into the nasopharynx include the auditory (eustachian) tubes, which help equalize pressure between the middle ear and the atmosphere, and the internal nares (choanae), which are the posterior openings of the nasal cavity into the nasopharynx. The fauces are the opening from the oral cavity into the oropharynx, not the nasopharynx. External nares are the openings of the nose to the external environment, and the nasolacrimal ducts drain tears from the eyes into the nasal cavity, not directly into the nasopharynx.
