what does the gallbladder do

The gallbladder is a small, pear-shaped organ located under the liver that stores and releases bile, a fluid produced by the liver that helps digest fats in the food we eat. Bile is released into the first section of the small intestine (the duodenum) when we eat fatty foods, where it helps break down and absorb fats from food. The gallbladder stores and concentrates bile from the liver, and when we eat, the gallbladder contracts and squeezes bile through the bile duct into the small intestine. The gallbladder is part of the digestive system, but it is not an essential organ, and most gallbladder issues are treated with the removal of the gallbladder through a cholecystectomy surgery
