ANGIOLOGY. 



the pancreas, crosses obliquely under the posterior vena cava, 



and entering the trans- 

 verse fissure of the liver, 

 is distributed to that 

 organ, along with the 

 vena porta; it supplies 

 the substance of the liver, 

 in which organ its ulti- 

 mate branches form three 

 communicating series, to 

 which the following terms 

 have been applied : the 

 rami vasculares, which 

 supply the walls of the 

 bile ducts and blood ves- 

 sels, as vasa vasorum ; 

 the rami capsulares, 

 which supply the capsule; 

 and the rami lohulares 

 supplying the substance 

 of the lobules. The 

 hepatic artery gives off 

 'pancreatic twigs to the 

 pancreas, and i\Le pyloric, 

 which passes over the 

 duodenum to the pylorus 

 and lesser curvature of 

 the stomach, anastomos- 

 ing with the left gastric. 

 The hepatic artery also 

 gives off the right gastro- 

 epiploic and duodenal. 

 The former, crosses the 

 duodenum, gains the 

 greater curvature of the 

 stomach, and inosculates 

 with the left gastro- 

 epiploic ; the latter pro- 

 ceeds along the curvature 

 of the duodenum, and 



anastomoses with a branch of the great mesenteric artery.
