What part of the GI tract prevents a person from choking while swallowing?

Question

Quizplus · Accepted Answer

The epiglottis is a flap of tissue located at the base of the tongue that prevents food or liquid from entering the trachea (windpipe) during swallowing, which could cause choking. It blocks the opening to the trachea and directs the food or liquid down the esophagus and into the stomach. The other options (mouth, pyloric sphincter, and upper esophageal sphincter) are not responsible for preventing choking during swallowing.
