Answer:
pharynx, larynx, trachea, bronchi
Explanation:
During the inhalation through the nose or mouth the air first enters the "pharynx" which is also called as throat,
then the air moves towards the "larynx" . Is a passage between the pharynx and the trachea

and then the air inhaled reaches to the "bronchi" of lungs.
hence, the correct order is "pharynx, larynx, trachea, bronchi"
