The gallbladder is a small organ located inferior and posterior to the liver. The gallbladder plays a vital role in the digestion of our food. The gallbladder contains bile produced in the liver until it is needed for digestion. It is a pear-shaped organ.
The end of the gallbladder narrows into a small bile duct known as the cystic duct, which connects the duct that carries bile from the liver. These ducts merge to form the common bile duct that extends to the wall of the duodenum. Bile is produced by cells in the liver and passed through the bile ducts.
