Explanation:

The respiratory tract's structure is as follows: air enters through the nose, goes to the nasal cavity, then to the pharynx. The larynx comes after the pharynx. The trachea is below the larynx, and the bronchus is a branch of the trachea. So after the nasal cavity, the next structure is the pharynx.
