Which part of the respiratory system follows the oropharynx in the airflow order?

The correct choice is laryngopharynx because it is the anatomical structure that directly follows the oropharynx in the pathway of airflow during respiration. The respiratory tract consists of various regions that facilitate the passage of air from outside the body to the lungs. After air enters the mouth or nose, it passes into the pharynx, which is divided into three sections: the nasopharynx, oropharynx, and laryngopharynx.

The laryngopharynx serves as a passage for both air and food and connects the oropharynx to the larynx (voice box) and esophagus. This positioning is crucial for ensuring that air is directed to the correct airway while allowing for the safe passage of food and liquids into the esophagus during swallowing. By understanding the sequence of airflow, it becomes clear that the laryngopharynx is the next region after the oropharynx before air continues to the trachea and into the bronchi.

The other options do not fit in the sequence after the oropharynx. The trachea is a lower airway structure that air reaches after passing through the laryngopharynx, while bronchioles are even further down the respiratory tract,
