What is the gallbladder?

The gallbladder is a small, sac-like organ that sits under the liver on the right side of your abdomen (belly). The gallbladder stores a greenish fluid called bile. Bile is made and released by the liver and then sent to the small intestine, where it helps the body break down and absorb food. Bile moves through a network of tube-like structures called bile ducts.
