The latest Rodrigo y Gabriella release!!! Yay!!!
Common bile duct is named common because it is formed by the cystic duct(connects the gall bladder to the bile duct) entering the duct formed from the fusion of the left and right hepatic duct not because it is "common" with the pancreatic duct. Typically(unless there is an anatomic variant--which happens rarely) the CBD and pancreatic duct are separate until they nearly exit the ampulla. Even the picture below is not fully accurate because the common channel is shorter than depicted.I get that it is supposed to be satire, but the pancreas does not produce bile. Bile is produced in the liver and stored in the gallbladder. Among other functions of the pancreas, it produces digestive enzymes notable Amylase (digests sugars), Lipase (digests fat), and Protease (digests protein). The pancreas and the biliary duct share the same exit into the intestine, called the Common Bile Duct, so perhaps this is where the confusion comes from.
As it should be.
