Final answer:
The laryngopharynx is connected to the larynx and the esophagus; it serves as a pathway for both air and food.
Step-by-step explanation:
The laryngopharynx extends inferiorly from the hyoid bone and is continuous with the larynx and esophagus. The laryngopharynx is part of the pharynx that serves as a passageway for both air and food. Anteriorly, it opens into the larynx, where air continues to the trachea and eventually the bronchial tree. Posteriorly, the inferior border of the laryngopharynx continues as the esophagus, which plays a role in guiding food and drink to the stomach. Therefore, the answer to the student's question is esophagus.
