The right renal vein is situated posterior to the descending part of the duodenum. [1] ... in front of and one behind the aorta this is called a circumaortic renal ...
These in turn unite and form veins which pass along the sides of the renal pyramids. The descending vasa recta have a non-fenestrated endothelium that contains a facilitated transport for urea; the ascending vasa recta have, on the other hand, a fenestrated endothelium.
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 ...
Splenic vein; Superior mesenteric vein; Inferior mesenteric vein; The superior mesenteric vein and the splenic vein come together to form the actual hepatic portal vein. 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.
The IMA arises from the anterior aspect of the abdominal aorta. [2] [3]Its origin is situated at the L3 vertebral level, [2] [3] below the origins of the two renal arteries, [3] 3-4 cm above the aortic bifurcation, [3] [2] at the level of the umbilicus, and posterior to the inferior border of the horizontal (III) part of the duodenum.
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.
It is covered, anteriorly, by the lesser omentum and stomach, behind which are the branches of the celiac artery and the celiac plexus; below these, by the lienal vein (splenic vein), are the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and the aortic plexus.
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 ...
