肝脏是人体很大的实质性器官,新生儿的肝占体重的5％,成人的肝为体重的2％。肝脏是最大的消化腺,能分泌胆汁。现已知其功能有1500多种,它几乎参与体内的一切代谢过程;肝脏也是人体的重要屏障器官,对外界进人体内的物质(如农药、药物)和体内产生的一些物质(如氨、胆色素等)能进行吞噬、分解或转化,达到解除毒性或变为易溶解的物质而被排除;肝还有一定的储血作用,心搏出的血液1/4流人肝内:胚胎时期肝有造血功能,正常成人的肝虽不参与造血,但仍有这种潜在能力,在机体需要时可恢复造血功能。肝的这些重要功能是以其形态结构为基础的。
The liver is a large, substantial organ of the human body, with 5% of the newborn’s liver and 2% of the adult’s liver. The liver is the largest digestive gland that secrete bile. It is known that its function is more than 1,500 kinds, it is almost involved in all the metabolic processes in the body; the liver is also an important barrier organ of the body, to the outside world into the body of substances (such as pesticides, drugs) and the body of some substances (such as ammonia, Bile pigment, etc.) can be phagocytized, decomposed or transformed to reach the release of toxic or become easily dissolved substances were excluded; the liver also has some blood storage, cardiac outflow of blood 1/4 flow in the liver: the embryonic period Hepatic hematopoiesis, normal adult liver although not involved in hematopoiesis, but still have this potential ability to restore hematopoietic function when the body needs. These important functions of the liver are based on their morphological structure.
