Question

Quizplus · Accepted Answer

The epiglottis is a flap of tissue that covers the glottis during swallowing, preventing food and drink from entering the respiratory passageways. The pharynx and larynx are also involved in swallowing, but the specific structure that prevents food and drink from entering the respiratory passageways is the epiglottis. The trachea is the main airway that brings air into the lungs and does not play a role in swallowing.
