The following are the branches of the hepatic artery :

2. A. g astro. d uodena,i,{ A : F 



3. A. hepatic, prop. {**&.;! *" 



The right gastric artery (O.T. pyloric] is a small artery 

 which springs from the hepatic artery at the pylorus, and 

 then runs from right to left, along the lesser curvature of the 

 stomach, between the two layers of the lesser omentum. It 

 ends by inosculating with the left gastric ; the accompanying 

 vein terminates in the portal vein. 



The gastro-duodenal artery arises close to the right gastric 

 artery. It descends, 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 right gastro- 

 epiploic branches (Fig. 140). 



The superior pancreatico - duodenal artery 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 right gastro-epiploic artery is directed from right 

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

 the anterior two layers of the greater omentum. It gives 

 branches upwards to both surfaces of the stomach, and 

 downwards to the greater omentum ; and it ends by anas- 

 tomosing with the left gastro-epiploic branch of the splenic 

 artery. 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. The cystic artery divides into two twigs ; 

 one of the two ramifies in the areolar tissue between the 

 over and gall-bladder, and the other upon the inferior surface
