一、什么是系统工程人体就是由许多个不同的系统组成的,每一个系统又由几个器官组成,例如人的呼吸系统主要包括鼻子、气管和肺三部分,它们的规模大小和活动,配合得很灵巧,使人们呼吸自如,能够恰当地供给人们活动所需的氧气和排出的二氧化碳。所以呼吸系统可以说是一个系统工程设计在人体构造上的现体。 First, what is the system engineering The human body is composed of many different systems, each system consists of several organs, such as the human respiratory system, including the nose, trachea and lungs in three parts, their size and activity, with the It is smart enough to breathe freely and to supply the oxygen and emitted carbon dioxide that people need for their activities. Therefore, the respiratory system can be said to be a system engineering design body in the body.
