Morphology

posterior + naris

The meaning is directly compositional: 'posterior' (at the rear) modifies 'naris' (nasal opening), yielding 'rear nasal opening' which matches the definition. This adjective+noun anatomical naming is a transparent, predictable combination, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Posterior naris comes from Latin words: posterior meaning 'back' and naris meaning 'nostril'. So it names the openings at the back of the nose that lead to the throat.
