8 PHYSIOLOGY OF LIVER. 



inter-lobular ducts; from thence it is poured into thn 

 biliary vaginal plexuses of the portal canal; thence into 

 the excreting ducts, by which it is carried to the gall- 

 bladder, and from thence into the duodenum, or the first 

 stage of the small intestines; where it comes in contact 

 with the pancreatic juice, and the chyme from tin* 

 stomach, which compound converts the latter into chyle. 



The hepatic artery distributes branches through 

 every portal canal, and gives oil' what is trnn< 

 branches, which form a vaginal //> tVoni

 terminate ultimately in the lulu/' 

 the portal vein. The artery ramifies abundantly in tin' 

 coats of the hepatic ducts, enabling them to provide 

 their mucous secretions, and suppl nutrient
