Duodenum (organ): The duodenum is the first section of the small intestine. It is a hollow muscular tube that connects the stomach to the jejunum, the second portion of the small intestine. Partially digested food, or chyme, is moved from the stomach through the pyloric sphincter into the duodenum through the action of peristalsis. The duodenum continues the process of digestion using bile and pancreatic juice, which are secreted into the duodenum through ducts. After digestion, nutrients are absorbed into the body in the duodenum.
Conditions that afflict the duodenum include duodenal ulcer, small intestine cancer, celiac disease, Crohn's disease, and paralytic ileus.
