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 secreted by liver cells and travels through the hepatic duct system into the small intestine where it is used to break down fat molecules.

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

　　The liver also plays a major role in the regulation of blood glucose (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 cellular waste and breaks down harmful substances, like alcohol.

　　肝的消化功能

　　由于機(jī)體是一個(gè)大的化學(xué)工廠，肝臟產(chǎn)生、調(diào)節(jié)和儲(chǔ)存一系列物質(zhì)用于胃腸道，它有許多重要的消化功能。

　　肝進(jìn)行消化的化學(xué)性物質(zhì)是膽汁。就餐時(shí)，肝細(xì)胞分泌的膽汁通過(guò)肝管系統(tǒng)進(jìn)入小腸，消化脂肪微粒。

　　在兩餐之間，膽汁被儲(chǔ)存在膽囊。膽汁還用于肝從血液排除毒素廢物。

　　肝臟在調(diào)節(jié)血液葡萄糖（血糖）的作用中也起著非常重要的作用。肝臟合成、分解和儲(chǔ)存氨基酸、蛋白質(zhì)和脂肪。它儲(chǔ)存一些重要的維生素，如B12和維生素A。肝也代謝細(xì)胞廢物和分解有害物質(zhì)，如酒精。
