The artery supplies the anterior and posterior sides of the duodenum and head of pancreas, with the anterior branch supply the anterior surface and similarly for the posterior. The artery supplies the part of the duodenum proximal to the level of the major duodenal papilla of the descending part of the duodenum. [3]
The celiac artery supplies the liver, stomach, spleen and the upper 1/3 of the duodenum (to the sphincter of Oddi) and the pancreas with oxygenated blood. Most of the blood is returned to the liver via the portal venous system for further processing and detoxification before returning to the systemic circulation via the hepatic veins.
The pancreas has a rich blood supply, with vessels originating as branches of both the coeliac artery and superior mesenteric artery. [7] The splenic artery , the largest branch of the celiac trunk, runs along the top of the pancreas, and supplies the left part of the body and the tail of the pancreas through its pancreatic branches, the ...
One of these, larger than the rest, is sometimes given off near the tail of the pancreas; it runs from left to right near the posterior surface of the gland, following the course of the pancreatic duct, and is called the greater pancreatic artery.
In human anatomy, the pancreatic veins consist of several small blood vessels which drain the body and tail of the pancreas, and open into the trunk of the great pancreatic vein. References [ edit ]
In human anatomy, the greater pancreatic artery (great pancreatic artery or arteria pancreatica magna), is the largest artery that supplies the pancreas. It arises from the splenic artery . [ citation needed ]
The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest. That is why the total liver blood flow is quite high, at about 1 litre a minute and up to two litres a minute. That is on average one fourth of the average cardiac output at rest.
The blood leaves the liver to the heart in the hepatic veins. The portal vein is not a true vein , because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system , one of three portal venous systems in the human body; the others being the hypophyseal and renal portal ...
