Question

Quizplus · Accepted Answer

The epiglottis is a flap of tissue that prevents food or liquid from entering the trachea and lungs when swallowing. It blocks the opening of the larynx and directs the food towards the esophagus. The trachea (A) is a tube that connects the larynx to the lungs and is not involved in the process of swallowing. The pharynx (B) is a common passage for both food and air, and different structures prevent food from entering the airway during swallowing. The esophageal sphincter (C) is located at the lower end of the esophagus and prevents stomach acid and partially digested food from flowing back into the esophagus.
