MCQ IN MEDICINE

Detailed explanation-1: -Both air and ingested food pass through the oropharynx and through the laryngopharynx below. The laryngopharynx lies posterior to the epiglottis and connects to the larynx (superiorly) and the esophagus (inferiorly). As we breathe, the epiglottis stays up and air passes freely between the laryngopharynx and the larynx.

Detailed explanation-2: -The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs. The structure of the larynx is formed by several pieces of cartilage.

Detailed explanation-3: -Air enters the body through the mouth or nose and quickly moves to the pharynx, or throat. From there, it passes through the larynx, or voice box, and enters the trachea.
