内分泌系统是动物体内一个非常重要的调节系统。近年来随着生物化学、分子生物学、免疫学、免疫病理学等学科的发展,人们对内分泌系统的整体认识有了很大提高。一、内分泌系统传统的内分泌系统(endocrine system)概念是与内分泌腺(endocrine glands)密切相联的。随着科学研究的不断深入,证明具有内分泌作用的细胞即内分泌细胞,不但集中于某些腺体,而且还大量地分布在机体的一些器官中,例如消化道、肾脏、肺脏、肝脏、心脏等。其中消化道是体内最大的内分泌器官。所谓APUD系统的
The endocrine system is a very important regulation system in animals. In recent years, with the development of biochemistry, molecular biology, immunology, immunopathology and other disciplines, the overall understanding of the endocrine system has been greatly improved. First, the endocrine system The traditional endocrine system (endocrine system) concept is closely linked with the endocrine glands (endocrine glands). With the deepening of scientific research, endocrine cells that prove endocrine cells that endocrine cells, not only concentrated in some glands, but also widely distributed in some organs of the body, such as the digestive tract, kidneys, lungs, liver, heart, etc. . Which the digestive tract is the body’s largest endocrine organ. The so-called APUD system
