from the hepatic at the pylorus, and then runs from right to 

 left, along the lesser curvature of the stomach, between the two 

 layers of the gastro-hepatic omentum. It ends by inosculat- 

 ing with the left gastric ; the accompanying vein terminates 

 in the portal vein. 



The Arteria G astro- Duodenalis arises close to the pyloric 

 artery, and is directed downwards, behind the first part of the 

 duodenum, in a groove on the anterior aspect of the neck of 

 the pancreas. At the lower border of the duodenum it ends 

 by dividing into the superior pancreatico-duodenal and the 

 right gastro-epiploic branches (Fig. 170). 



The Arteria Pancreatico-Duodenalis Superior runs first to 

 the right and then downwards between the head of the 

 pancreas and the duodenum. It anastomoses with the inferior 

 pancreatico-duodenal branch of the superior mesenteric artery 

 forming an arch round the head of the pancreas. It gives 

 branches to both the duodenum and the pancreas. The 

 pancreatico-duodenal veins join the superior mesenteric vein. 



The Arteria Gastro-Epiploica Dextra is directed from right 

 to left, along the greater curvature of the stomach, and 

 between the two anterior layers of the great omentum. It 

 gives branches upwards to both surfaces of the stomach, 

 and downwards to the greater omentum, and ends by anasto- 

 mosing with the left gastro-epiploic branch of the splenic. 

 The right gastro-epiploic vein joins the superior mesenteric 

 vein. 



The right and left hepatic arteries, the terminal branches 

 of the hepatic, diverge from each other, and sink into the 

 liver at the two extremities of the porta hepatis. From 

 the right hepatic a small branch called the cystic is given to 

 the gall-bladder. This divides into two twigs, one of which 

 ramifies in the areolar tissue between the liver and gall- 

 bladder and the other upon the inferior surface of the gall- 

 bladder, between it and its peritoneal covering. 



The cystic vein joins the vena portae or its right branch. 



Arteria Lienalis (Splenic Artery). The splenic artery 

 is the largest branch of the cceliac artery. It takes a wavy 

 or tortuous course, along the upper border of the pancreas 

 behind the omental bursa, towards the left side, and ends, in 

 front of the left kidney, by dividing into five or six branches, 

 which enter the hilus of the spleen. 



It is accompanied by the splenic vein, which, however,
