**The ascending duodenum is shorter and bends ventrally to enter the mesentery and becomes the jejunum.

*Mesoduodenum attaches the duodenum to the dorsal abdominal wall.
*Mesoduodenum attaches the duodenum to the dorsal abdominal wall.
**Within the mesoduodenum is the right lobe of the [[Pancreas - Anatomy & Physiology|pancreas]].
*The pancreatic and bile ducts open into the duodenum.
*The pancreatic and bile ducts open into the duodenum.
**The bile duct and one of the pancreatic ducts discharge into the proximal part of the duodenum by separate ''major duodenal papillae''.
**The bile duct and one of the pancreatic ducts discharge into the proximal part of the duodenum by separate ''major duodenal papillae''.
**The second pancreatic duct discharges a little more distally on a smaller papilla.
**The second pancreatic duct discharges a little more distally on a smaller papilla.
*The cranial part of the descending duodenum is attached to the liver by the '''hepatoduodenal ligament'''. This is a remnant of the [[Forestomach - Anatomy & Physiology|ventral mesogastrium]] in the embryo.
**The bile duct runs within the hepatoduodenal ligament.
