The Human Gallbladder Attached To The Biliary Tree

Description

Arising from the visceral surface of the liver, the pear-shaped gallbladder is shown seated in its fossa between the right and quadrate lobes, with the fundus projecting anteriorly and inferiorly toward the abdominal wall. The neck narrows into the cystic duct, which courses posteromedially to join the common hepatic duct and form the common bile duct within the extrahepatic biliary tree. As the animation progresses, the branching ducts appear in sequence, clarifying how bile flows from the right and left hepatic ducts into the common hepatic duct, then either continues distally or diverts into the gallbladder for storage. Ductal geometry matters. That relationship underpins most everyday biliary pathology. Gallstones lodging at the cystic duct or Hartmann pouch explain biliary colic and acute cholecystitis, while a stone at the distal common bile duct (choledocholithiasis) can obstruct pancreatic outflow and precipitate gallstone pancreatitis. By animating continuity and directionality of flow, the sequence makes it easier to grasp why jaundice patterns differ between isolated cystic duct obstruction and common bile duct obstruction, and why endoscopic access targets the major duodenal papilla rather than the gallbladder itself. Use this asset for hepatobiliary blocks in gross anatomy and GI physiology courses, for surgical teaching on laparoscopic cholecystectomy orientation and duct identification, and for patient-facing explainers on ERCP, biliary stenting, or cholecystectomy indications. It also fits figure panels in review articles on obstructive jaundice and acute cholecystitis where a clear extrahepatic duct map is needed.
