The primary function of the gallbladder is to store and concentrate bile produced by the liver. Bile is a digestive fluid essential for breaking down fats and absorbing fat-soluble vitamins in the small intestine. When food containing fat enters the small intestine, the gallbladder releases bile into the digestive tract, aiding in the emulsification and breakdown of fats. This function is vital for efficient digestion and nutrient absorption. Dysfunction or removal of the gallbladder can impact fat digestion, leading to dietary adjustments for affected individuals.
