The duodenojejunal flexure is surrounded by the suspensory muscle of the duodenum. [4]: 274 It is retroperitoneal, so is less mobile than the jejunum that comes after it, helping to stabilise the jejunum. [5] The duodenojejunal flexure lies in front of the left psoas major muscle, the left renal artery, and the left renal vein.
Due to the anatomical position of the aorta, the inferior vena cava, and the kidneys, the right renal artery is normally longer than the left renal artery. [1] [6] The right passes behind the inferior vena cava, the right renal vein, the head of the pancreas, and the descending part of the duodenum. It’s somewhat lower than the left one. Left ...
The anterior superior pancreaticoduodenal vein drains into the right gastroepiploic vein, as do the veins of the lower first part of the duodenum and the pylorus (subpyloric veins). The upper first part of the duodenum is drained by suprapyloric veins, which can drain into the portal vein or the posterior superior pancreaticoduodenal vein ...
the third part of the duodenum, a segment of the small intestines (can be compressed by the SMA at this location, leading to superior mesenteric artery syndrome). uncinate process of pancreas - this is a small part of the pancreas that hooks around the SMA. The SMA typically runs to the left of its associated vein, the superior mesenteric vein ...
Small intestine: 19. Duodenum 20. Jejunum 21–22. Right and left kidneys The front border of the liver has been lifted up (brown arrow). [1] The major duodenal papilla is situated in the second part of the duodenum, 7–10 cm from the pylorus, at the level of the second or third lumbar vertebrae.
The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk , the superior mesenteric artery , and the inferior mesenteric artery .
The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output .
