of the stomach, forming the lower boundary of the foramen of Winslow. It then 

 passes upward between the layers of the lesser omentum, and in front of the fora- 

 men of Winslow, to the transverse fissure of the liver, where it divides into two 

 branches, right and left, which supply the corresponding lobes of that organ, 

 accompanying the ramifications of the vena portge and hepatic duct. The hepatic 

 artery, in its course along the right border of the lesser omentum, is in relation 

 with the ductus communis choledochus and portal veins, the duct lying to the 

 right of the artery and the vena portse behind. 

 Its branches are the

The pyloric branch arises from the hepatic, above the pylorus, descends to the

supplying it with branches and inosculating with the gastric branches of the coro- 

 nary artery. 



The gastro-duodenalis (Fig. 309) is a short but large branch, which descends, 

 near the pylorus, behind the first portion of the duodenum, and divides at the 

 lower border of this viscus into two branches, the gastro-epiploica dextra and the 

 pancreatico-duodenalis superior. Previous to its division, it gives off' two or three 

 small inferior pyloric branches to the pyloric end of the stomach and pancrra-.
