where does bile go after it leaves the gallbladder?
into the small intestine
normally, the downstream gallbladder stores and concentrates the bile which originates in liver hepatocyte cells and is released into the microscopic component of the biliary 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 biliary dyskinesia.
biliary dyskinesia
it is divided into three sections, a fundus, body and neck. the neck tapers and connects to the biliary tract via the cystic duct, which then joins the common hepatic duct to form the common bile duct. at this junction is a mucosal fold called "hartmann's pouch", where gallstones commonly get stuck. the muscular layer of the body is of smooth muscle tissue that helps the gallbladder contract, so that it can discharge its bile into the bile duct. the gallbladder needs to store bile in a natural, semi-liquid form at all times. hydrogen ions secreted from the inner lining of the gallbladder keep the bile acidic enough to prevent hardening. to dilute the bile, water and electrolytes from the digestion system are added. also, salts attach themselves to cholesterol molecules in the bile to keep them from crystallising. if there is too much cholesterol or bilirubin in the bile, or if the gallbladder doesn't empty properly the systems can fail. this is how gallstones form when a small piece of calcium gets coated with either cholesterol or bilirubin and the bile crystallises and forms a gallstone. the main purpose of the gallbladder is to store and release bile, or "gall". bile is released into the small intestine in order to help in the digestion of fats by breaking down larger molecules into smaller ones. after the fat is absorbed, the bile is also absorbed and transported back to the liver for reuse.
