生物机体与自动机器之间,有着许多共同的东西,例如均存在各种类型的反馈,以实现其内部的调节控制。在生物系统的各个结构层次中,都已发现存在负反馈,保证内部的某些参数,如物质浓度的相对恒定。特别是在整体水平上的生理调节系统,与自动调节系统极为相似,人体的内环境的各个参数,包括体温、血压,呼吸的通气量和频率,血液中葡萄糖、各种激素以及各种离子的含量、水份等,都是由负反馈
There are many things in common between a living body and an automatic machine. For example, there are various types of feedback in order to realize its internal control. At each structural level of the biological system, negative feedback has been found to ensure that certain internal parameters, such as the relatively constant concentration of the substance. Especially in the overall level of physiological regulation system, and automatic regulation system is very similar to the body’s internal environment parameters, including body temperature, blood pressure, respiratory ventilation and frequency, blood glucose, various hormones and various ions Content, moisture, etc., are negative feedback
