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 ...
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 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.
Microscopic section through a small portal vein branch inside the liver (×250 magnified) The portal venous system is responsible for directing blood from parts of the gastrointestinal tract to the liver. Substances absorbed in the small intestine travel first to the liver for processing before continuing to the heart.
The superior mesenteric artery and vein are anterior to the third part of the duodenum. [9]: 274 This part may be compressed between the aorta and SMA causing superior mesenteric artery syndrome. The fourth or ascending part of the duodenum passes upward, joining with the jejunum at the duodenojejunal flexure. The fourth part of the duodenum is ...
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 ...
The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
