choana
This term is a specialized anatomical descriptor used primarily in medical, veterinary, and biological contexts. It describes the internal openings of the nasal passage, and its usage is restricted to technical descriptions of respiratory anatomy or surgical procedures involving the nasopharynx.
Because it refers to a specific anatomical structure, it is used as a countable noun when referring to the pair of apertures (the left and right choanae) found in most vertebrates.
