Final answer:
The correct pathway of air from the nasal cavity to the bronchioles is nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.
Step-by-step explanation:
The correct sequence when tracing the path of air from the upper to lower respiratory tract is from the nasal cavity, through the pharynx and larynx, down the trachea, into the bronchi, and finally through the bronchioles. The correct order of structures that air passes through from the pharynx to the bronchioles during inhalation is: pharynx → larynx → trachea → bronchi → bronchioles.
