Quizplus · Accepted Answer

The duodenum is the portion of the small intestine that is closest to the stomach. It is responsible for receiving partially digested food from the stomach and neutralizing the acid that was added to the food during the digestion process. The other choices are parts of the large intestine (colon and cecum) or other parts of the small intestine (ileum and jejunum) that are located further down the digestive tract.
