Which flap of cartilage covers the trachea during swallowing?

Explanation:
During swallowing, the body protects the airway by using a flap of elastic cartilage called the epiglottis. This flap sits at the opening of the larynx, which leads to the trachea. When you swallow, the larynx rises and the epiglottis tilts downward to cover the laryngeal inlet, effectively sealing the entrance to the trachea and directing the food toward the esophagus. This mechanism prevents food or liquid from entering the airway, which is the key reason the epiglottis is the correct answer.
