Bile Duct System and Gallbladder. The bile duct (biliary) system provides the channels through which bile is transported from the liver to the duodenum (through the papilla of Vater). The liver is found in the right upper corner of the abdomen, immediately below the diaphragm. In health it weighs 3-4 pounds.
The human liver produces approximately 400ml to 800ml of bile each day. Hepatocytes of the liver secrete bile, which is then released into the canaliculi before entering the bile ducts.The bile ducts add to this secretion a liquid rich with bicarbonates. Next, a hormone called cholecystokinin (CCK), causes gall bladder contraction, which discharges bile into the duodenum.he human liver produces approximately 400ml to 800ml of bile each day. Hepatocytes of the liver secrete bile, which is then released into the canaliculi before entering the bile ducts.
