The '''duodenojejunal flexure''' or '''duodenojejunal junction''' is the border between the [[duodenum]] and the [[jejunum]].
The ascending portion of the [[duodenum]] ascends on the left side of the [[aorta]], as far as the level of the upper border of the second [[lumbar vertebra]], where it turns abruptly forward to become the [[jejunum]], forming the '''duodenojejunal flexure'''.
It lies in front of the left [[Psoas major]] and left renal vessels, and is covered in front, and partly at the sides, by [[peritoneum]] continuous with the left portion of the [[mesentery]].
