Gall bladder
The gallbladder is a pear-shaped organ in your abdomen. It stores about 50 ml of acidic liquid (bile) until the body needs it for digestion. That liquid helps digest fat. The gallbladder is about 7-10cm long in humans. It is dark green in color because of the bile in it. It is connected to the liver and the duodenum by the biliary tract.
