The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum.

After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas.

Absorption of vitamins, minerals, and other nutrients begins in the duodenum.

The duodenum is the first part of the intestine; it is the place that the stomach empties it's contents into. Along with that, the duodenum is an essential digestion site. The pancreas, liver and gallbladder all secrete important digestive enzymes into the duodenum. The enzymes digest fats, proteins and fats. Much activity goes on in the duodenum, which is why the duodenum is so crucial for digestion.
