Question

Quizplus · Accepted Answer

The main function of the esophagus is to transport the bolus (the chewed and moistened food) from the pharynx to the stomach. No chemical digestion of proteins or provision of saliva occurs in the esophagus. While the esophagus does play a role in preventing food or liquid from entering the trachea, its primary function is not to protect the body from disease.
