THE CIRCULATORY SYSTEM. 



Branches of the cceliac artery: 



i. A. hepatica (W). The hepatic artery passes cranioven- 

 trad, pierces the descending limb of the great omentum and 

 passes craniad to the liver, 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 Glisson. 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 (/), and A. gastroepiploica 

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

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