Anterior view (top) and transverse section (bottom) of development of pancreas. Here, a connecting segment unites the dorsal pancreatic duct to the ventral duct. Duodenal end of dorsal duct atrophies.

Schematic illustration of anterior view of liver in situ. Liver pictured on a page in a book with surrounding anatomy; jejunum, ileum, and ascending, transverse, and descending colon have been removed.

Anterior view of lesser and greater omenta. Stomach is inflated with air, and left part of liver is cut away, outline of a complete liver demarcated with a dotted line.

Two simple drawings of the liver, anterior view (top), posteroinferior view (bottom). In both, the segments of the liver are identified by Roman numerals.

Anterior view of deep anterior surface of gallbladder, vessels in porta hepatis, and fossa of gallbladder. Liver has been reflected superiorly, gallbladder freed from its bed and turned inferiorly and to the right.

Anterior view of exposed bile duct. Lesser omentum and transverse colon removed, peritoneum cut along right border of duodenum, duodenum swung anteriorly.

Anterior view (top) and transverse section (bottom) of development of pancreas. Here, the 2nd, or descending, part of duodenum rotates to bring ventral bud and bile duct posterior to dorsal bud of pancreas.

Anterior view (top) and transverse section (bottom) of development of pancreas. Here, small primitive ventral bud arises in common with bile duct and larger primitive dorsal bud arises independently from duodenum.

Anterior and interior view of the gallbladder.
