Quizplus · Accepted Answer

The epiglottis is a small flap of tissue in the pharynx that covers the opening to the trachea (windpipe) during swallowing to prevent food or liquid from entering the lungs. The glottis refers to the space between the vocal cords in the larynx and is not involved in preventing aspiration during swallowing. The parietal and visceral pleura are membranes that line the lungs and chest cavity and are not directly involved in the swallowing process.
