The bile juice secreted by the liver is stored in a sac called [[1]].

The gallbladder is a sac-like structure that stores bile juice produced by the liver. 

The gallbladder is located beneath the liver and is in charge of storing and releasing bile as needed into the small intestine. 

Bile is a yellow-green fluid that aids in the digestion and absorption of fats in the small intestine. 

The gallbladder stores bile produced by the liver until it is required for digestion, at which point it is released into the small intestine via the bile duct. 

This regulated bile release ensures a constant supply of bile for fat digestion and helps to maintain the proper bile balance in the digestive system.
