Hello,

The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen.

Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract.

the gallbladder is a small hollow organ where bile  is stored and concentrated before it is released into the small intestine.

Hope that helps.
