There it enters the superior end of the common bile duct and either empties into the second (and [[retroperitoneal]]) part of the duodenum, or enters the cystic duct to be stored in the gallbladder. The inferior end of the common bile duct merges with the large [[pancreatic duct]] (duct of Wirsung) from the [[pancreas]], into the [[ampulla of Vater]]. There, the two ducts are surrounded by the muscular hepatopancreatic sphincter ([[sphincter of Oddi]]) which if contracted, prevents [[bile]] from entering the small intestine. ==Additional images== <gallery> Image:Illu pancrease.jpg|Region of pancreas Image:Gray848.png|The celiac ganglia with the sympathetic plexuses of the abdominal viscera radiating from the ganglia.
