False-colour radiogram of the human gall bladder (balloon-like) and bile ducts, obtained following the injection of a radio-opaque contrast medium via an endoscope in the duodenum (part of the gut). The spine is visible at far left and the large green-yellow tube is part of the endoscope (duodenoscope), through which the contrast medium is passed. The gall bladder is the storage organ for bile produced in the liver, under which it is located. Bile is released into the duodenum via the common bile duct during digestion.
