What is cholelithiasis?
Gallstone, in the gallbladder
What is cholecystectomy?
Removal of gallbladder
What is choledocholithiasis?
Gallstone, in the bile duct
What is cholangitis?
Infection of the bile duct
Describe the passage of bile from liver to gallbladder
Biliary canaliculi in liver Interlobular bile ducts Septal bile ducts Intrahepatic ducts R/L hepatic ducts Common hepatic duct Common bile duct
Where does the common hepatic bile duct descend?
In the free edge of the lesser omentum (with the portal vein) to join the cystic duct to give the common bile duct
Where does the common bile duct descend?
Behind the duodenum, through the head of the pancreas to join with the pancreatic duct, and opens into the ampulla of Vater
What structure regulates bile flow?
Sphincter of Oddi
Where does the gallbladder lie?
In the gallbladder fossa on the right inferior edge of the hepatic quadrate lobe
Why/how is the cystic duct constantly open?
Due to spiral folding of the mucus membrane to let bile get to the gallbladder from the liver when the bile duct is closed, and to let bile get to the duodenum from the gallbladder when gallbladder contracts.
