AB The  hepatobiliary  system  originates  as  a  cluster  of  endodermal  cells  that  forms  a  diverticulum  from  the  duodenal  region  of  the  primitive  embryonic  gut.  The  diverticulum  divides  into  2  components  between  gestation  weeks  18  and  22.  (1)  A  solid  cranial  component  (the  pars  hepatica)  gives  rise  to  the  liver  and  intrahepatic  portion  of  the  biliary  system,  and  (2)  a  hollow  caudal  component  (the  pars  cystica)  gives  rise  to  the  gallbladder  (GB)  and  extrahepatic  portion  of  the  biliary  system.
