External Nares

External nares are the nostrils, the external openings of the nasal cavity, responsible for the intake of air into the respiratory system.

Nasal Cavity

The large air-filled space above and behind the nose in the middle of the face, which filters, warms, and humidifies inhaled air.

Soft Palate

The Soft Palate is the soft tissue constituting the back of the roof of the mouth, separating the mouth from the nasopharynx, and is crucial in swallowing and speech.
