本文比较了九个门脉系的有关资料,提出所有的门脉系都是连结内分泌腺和相应靶的信息通道。内分泌腺、门脉系和靶是一个完整的內分泌调节单位。另外,作者将循环系统分为左、右心门脉系两部分,从而建立了广义门脉系概念。它表明内分泌的门脉系调节是循环系调节的最基本形式,此推论支持汤健的观点。 This article compares data from the nine portal systems and suggests that all portal systems are information channels that link the endocrine glands and the corresponding targets. Endocrine glands, portal systems and targets are a complete unit of endocrine regulation. In addition, the author divides the circulatory system into two parts, left and right ventricular system, thus establishing the concept of generalized portal system. It shows that the regulation of endocrine portal system is the most basic form of circulatory regulation, this corollary supports Tang Jian’s point of view.
