Gallbladder
A pear-shaped organ just below the liver that stores the bile secreted by the liver.
During a fatty meal, the gallbladder contracts, delivering the bile through the bile ducts into the intestines to help with digestion.
Abnormal composition of bile leads to formation of gallstones, a process termed cholelithiasis.
The gallstones cause cholecystitis, inflammation of the gallbladder.</P> NTER><IMG height=348 alt='Illustration of Gallstones forming in the Gallbladder' src='http://images.medicinenet.com/images/illustrations/gallbladder.jpg' width=300 border=0></CENTER>
