Origin of gallbladder:
gallbladder, gall bladder(noun)
a muscular sac attached to the liver that stores bile (secreted by the liver) until it is needed for digestion
In vertebrates the gallbladder is a small organ that aids mainly in fat digestion and concentrates bile produced by the liver. In humans, the loss of the gallbladder is, in most cases, easily tolerated. The surgical removal of the gallbladder is called a cholecystectomy.
