The Cystic Duct

  1. Bile can easily pass into the gallbladder when the bile duct is closed by the choledochal sphincter and/or the hepatopancreatic sphincter.
  2. Bile can pass the opposite direction, into the duodenum, when the gallbladder contracts. A hormonal mechanism (cholecystokinin) is involved in gallbladder contraction.

Arterial Supply of the Bile Duct
