Gallbladder (Chinese medicine) : ウィキペディア英語版
Gallbladder

In vertebrates the gallbladder (also gall bladder, biliary vesicle or cholecyst), is a small organ where bile (a fluid produced by the liver) is stored and concentrated before it is released into the small intestine. Humans can live without a gallbladder. The surgical removal of the gallbladder is called a cholecystectomy.
==Structure==
The gallbladder is a hollow organ that sits just beneath the right lobe of the liver. In adults, the gallbladder measures approximately in length and in diameter when fully distended. The gallbladder has a capacity of about 100 mL.〔
The gallbladder is shaped like a tapered sac, with the open end opening into the biliary tree and the cystic duct. Anatomically, the gallbladder is divided into three sections: the ''fundus'', ''body'', and ''neck'': The ''fundus'' is a rounded end that faces the front of the body.〔 The ''body'' is in contact with the liver, lying in the gallbladder fossa, a depression at the bottom of the liver.〔 The ''neck'' tapers and is continuous with the cystic duct, part of the biliary tree. The cystic duct unites with the common hepatic duct to become the common bile duct. At the junction of the neck of the gallbladder and the cystic duct, there is an out-pouching of the gallbladder wall forming a mucosal fold known as Hartmann's pouch, where gallstones commonly get stuck.
The angle of the gallbladder is located between the costal margin and the lateral margin of the rectus abdominis muscle. The fundus is at the same level as the transpyloric plane.
