Digestive Function of the Liver

　　Sometimes referred to as the great chemical factory of the body, the liver creates, regulates, and stores a variety of substances used by the gastrointestinal system, and it serves a number of important digestive functions.

　　The main digestive chemical synthesized by the liver is bile. During a meal, bile is secreted¹ by liver cells and travels through the hepatic duct system into the small intestine² where it is used to break down fat molecules³.

　　Between meals, bile is stored in the gall⁴ bladder. Bile further serves as a waste disposal system for toxins⁵ removed from the blood by the liver.

　　The liver also plays a major role in the regulation of blood glucose⁶ (blood sugar). The liver synthesizes, dissolves, and stores amino acids, protein, and fat.It stores several important vitamins like B12 and Vitamin A. The liver also disposes of cellular⁷ waste and breaks down harmful substances, like alcohol.

　　在两餐之间，胆汁被储存在胆囊。胆汁还用于肝从血液排除毒素废物。
