The liver is the organ in the human body that produces bile. Bile is a digestive fluid that the liver continuously produces and stores. It plays a crucial role in the digestion and absorption of fats. The liver secretes bile into small ducts, which then carry it to the gallbladder for storage. When you eat a meal that contains fats, the gallbladder releases bile into the small intestine to aid in the breakdown and absorption of dietary fats. Bile contains substances that emulsify fats, making them more accessible to digestive enzymes and allowing for efficient fat digestion and absorption in the small intestine.
