The external openings of the nasal cavity that admit air to the lungs are called ?

Explanation

Nostrils are the two openings in your nose that let air enter and leave your body. When you breathe in, air comes through your nostrils into your nasal cavity.

The oesophagus is for food, not air. The larynx and trachea are inside the breathing system, not external openings. They come after the nostrils in the breathing pathway.

Nostrils are the only external openings that admit air to the lungs. They are the entry points where breathing begins.
