what is the function of gallbladder in our body?

The gallbladder is a small, pear-shaped organ located just beneath your liver. Its main function is to store and concentrate bile, a digestive fluid made by the liver. 

When you eat fatty foods, the gallbladder releases bile into the small intestine to help break down and digest fats.

In simple terms, the gallbladder acts like a storage tank, holding bile until your body needs it for digestion. 

Without the gallbladder, bile flows directly from the liver to the intestine, but having the gallbladder helps your body digest fats more efficiently.
