The gallbladder has a capacity of about 50 millilitres (1.8 imperial fluid ounces). [2] The gallbladder is shaped like a pear, with its tip opening into the cystic duct. [4] The gallbladder is divided into three sections: the fundus, body, and neck. The fundus is the rounded base, angled so that it faces the abdominal wall.
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter.

The anatomy and variant anatomy of this region is important during gallbladder removal to prevent iatrogenic injury to the common hepatic duct, bile duct, or right hepatic artery. [ 3 ] The cystic artery lies within the hepatobiliary triangle, which is used to locate it during a laparoscopic cholecystectomy .
