Normally, the downstream gallbladder stores and concentrates the bile which originates in liver hepatocyte cells and is released into the microscopic component of the<unk>  system by the liver. Through aggregating tubules of increasing diameter, the bile leaves the liver and reaches the upstream (proximal) component of the common bile duct. Apparently, the common bile duct beyond (distal to) the gallbladder tends to normally have a greater tone so that the bile backs up into the gallbladder. When bile enters the duodenum (the first part of the small intestine), it aids in digesting the fat within food leaving the stomach. When the bile can not be properly propelled from the not-mechanically-obstructed gallbladder or can not flow out of the end of the common bile duct properly, there is a state of<unk> . So,<unk>  is a dynamically (functional...not fixed mechanical) obstructive, pain-producing disorder. Obstruction by a stone or tumor is a static, mechanical obstruction and tends to produce a more intense pain known as<unk>  colic. Failure of the<unk>  sphincter of Oddi can be distinguished from failure of the pancreatic sphincter.
