<P> In vertebrates the gallbladder is a small organ where bile is stored and concentrated before it is released into the small intestine . In humans , it lies beneath the liver , although the structure and position of the gallbladder can vary significantly between animal species . It receives and stores bile , produced by the liver , via the common hepatic duct , and releases it via the common bile duct into the duodenum , where the bile helps in the digestion of fats . </P>
where do the ducts from the gallbladder end
