肝脏是维持人体正常生理活动的重要器官,它几乎参与体内的一切代谢和重要的生理过程,如食物的消化与吸收,蛋白质(包括酶)、糖、脂类、维生素、激素、胆色素、胆汁酸等物质的代谢,代谢产物的分泌、排泄,药物和毒物等的生物转化,胎儿红细胞的生成与破坏,血液的凝固、抗凝固及纤维蛋白溶解过程,血容量的调节,体热的产生,以及水和电解质的平衡等。因此,肝脏是体内最重要的代谢器官,被称为人体内最大的“化工厂”或“物质代谢中枢”。肝脏所以具有如此重要的多种多样的代谢功能,是与其化学组成、形态结构及细胞群体动力学的特点密切相关的。
The liver is an important organ that maintains the body’s normal physiological activities. It participates in almost all metabolism and important physiological processes in the body, such as food digestion and absorption, proteins (including enzymes), sugars, lipids, vitamins, hormones, bile pigments Acid metabolism and other substances, secretion of excretion of metabolites, excretion, biotransformation of drugs and poisons, the formation and destruction of fetal red blood cells, blood coagulation, anti-coagulation and fibrinolysis process, blood volume regulation, body heat generation, As well as water and electrolyte balance. Therefore, the liver is the body’s most important metabolic organ, known as the body’s largest “chemical plant” or “material metabolism center.” So the liver has so important a variety of metabolic functions, is closely related to its chemical composition, morphological structure and characteristics of cell population dynamics.
