Figure 2 – Lateral view of the side of the nasal septum.
Likewise, people ask, where is the posterior nasal aperture?
The choanae (singular choana), posterior nasal apertures or internal nostrils are two openings found at the back of the nasal passage between the nasal cavity and the throat in tetrapods with secondary palates, including humans and other mammals (as well as crocodilians and most skinks).
