It's Connected to the Jejunum
The duodenum consists of three parts totaling 25 cm to 30 cm of the three- to five-meter of small intestines. The other two sections of the small intestine include the jejunum and ileum. Thus, the duodenum connects to the stomach and jejunum. Additionally, its walls include four tissue layers that match the rest of the tissue in the gastrointestinal tract.
The layers of the duodenum include the mucosa, submucosa, muscularis and serosa, with the mucosal layer as the inner surface of the small intestine.
