THE CIRCULATORY SYSTEM. 



Branches of the cceliac artery: 



I. A. hepatica [d). — The hepatic artery passes cranioven- 

 trad, pierces the descending Hmb of the great omentum and 

 passes craniad to the Hver, lying, together with the portal vein 

 and common bile-duct, in the ventral boundary of the foramen

epiploicum (foramen of Winslow) and contained, together with 

 the last-named vessels, in a fibrous sheath called the capsule 

 of GHsson. Just before entering the sheath it gives off the 

 gastroduodenalis {g). At its termination the hepatic artery 

 divides, sending branches to the lobes of the liver and a cystic 

 artery to the gall-bladder. 



a. A. gastroduodenalis {g). — This arises from the hepatic 

 near the pylorus and passes caudad, dividing one or two centi- 

 meters from its origin into three branches, A. pylorica (//), 

 A. pancreaticoduodenalis superior ij), and A. gastroepiploica 

 dextra (/). The pylorica (//) (which may arise directly from 

 the hepatic) passes to the pylorus, thence along the lesser cur-
