What Is the Duodenum?

7. Receives Digestive Juices
As mentioned earlier, the duodenum provides the site where digestive juices get into the digestive system. The liver and gall bladder release bile, while bicarbonate and digestive enzymes such as trypsin, lipase, and amylase are released from the pancreas.
All these secretions end up in the duodenum where they have roles in completing the digestion of foods. Brunners glands secrete mucus and some bicarbonate, whose role is to protect the duodenum from the abrasive action of gastric acid in the incoming, partially digested foods.
