During swallowing, which structure primarily prevents liquids and solids from entering the respiratory tract?

During swallowing, the epiglottis acts as a lid over the laryngeal inlet, preventing material from entering the airway. This leaf-shaped cartilage flips down as the larynx elevates, covering the opening to the trachea and directing the bolus into the esophagus. The glottis is the space between the vocal cords, which is protected when the epiglottis closes, but the actual structure blocking the airway is the epiglottis. This is why the epiglottis is the key safeguard against aspiration during deglutition.
