（单词翻译:单击）

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.
