What does the duodenum do to you?
It distributes bile and pancreatic acids to help break down food
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.
After it is made in the liver, bile is stored in the gallbadder, which is located just behind the liver. The bile duct links the gall bladder with the duodenum. When the partially digested stomach contents enter the duodenum, the bile travels from the gallbladder, through the bile duct and into the duodenum.
The duodenum is only the first portion of the small intestine. The small intestine comprises the duodenum, the jejunum, and the ileum. Following the ileum of the small intestine is the ileocecal valve, which separates the small intestine from the large intestine. The duodenum is separated from the stomach by the pyloric sphincter.
