  13. Liver development The gallbladder, bile ducts, and liver begin to develop duringthe 4th week of embryogenesis as a ventral bud from the mostcaudal aspect of the foregut (the future duodenum). This budis called the hepatic diverticulum, and it grows between thelayers of the ventral mesentery (Fig 1). The hepatic diverticulumhas two distinct components: pars hepatica and pars cystica(1). The pars hepatica, the most cranial component, gives riseto the liver, common hepatic duct, and intrahepatic bile ducts.The pars cystica, the most caudal component, gives rise to thecystic diverticulum. The cystic diverticulum is the anlage ofthe gallbladder and the cystic duct. The original hepatic diverticulumelongates to form the common bile duct. These structures beginas solid cords, but by the 8th week of gestation, a lumen hasbeen established throughout the biliary tract.
