Quizplus · Accepted Answer

The duodenum is the site where most digestion and absorption occur, particularly of nutrients such as iron, calcium, and magnesium. It receives partially digested food from the stomach and digestive enzymes from the pancreas and liver. The sphincter of Oddi controls the release of pancreatic and bile juices into the duodenum, but it does not pump food through it. The hepatic and splenic flexures are bends in the colon, not the duodenum.
