An understanding of the function of gallbladder is necessary to understand why gallbladder removal surgery is the solution for presence of gallstones. Gallbladder is the place where the bile, a potent digestive juice produced by the liver is stored in a very concentrated form. But before it is stored it is imperative to understand when it is stored. Every day about 800 – 1000 ml of bile is produced by the liver. There is a duct that runs from the liver to the duodenum that transports the bile produced. But there is a branch in that duct that branches straight into the Gallbladder.
