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]]. ==Additional images== <gallery> Image:Gray1042.png|Duodenojejunal fossa.
