TY - CHAP M1 - Book, Section TI - The Hepatobiliary System A1 - Wells, Robert G. PY - 2015 T2 - Diagnostic Imaging of Infants and Children 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.
