Question

The portion of food swallowed at one time, known as ____, is transported from the mouth to the stomach via the ____. ​

Quizplus · Accepted Answer

The portion of food swallowed at one time is called a bolus and it is transported from the mouth to the stomach via the esophagus. Option A is incorrect because a sphincter is a muscular valve that regulates the flow of material between two body regions and the epiglottis is a flap of tissue that closes off the trachea during swallowing to prevent choking. Option B is incorrect because chyme is the partially digested food that leaves the stomach and enters the small intestine, and the pyloric sphincter is the valve at the bottom of the stomach that controls the release of this partly digested mixture into the small intestine. Option D is incorrect because mucus is a slimy substance that protects the lining of the digestive tract and the large intestine is the last segment of the digestive system, where water is absorbed and feces are formed.
