摘要
With the development of manned spaceflight, more and more researches are involved in the area of gravitation physiology. When astronauts are exposed to microgravity, a series of special physiological or pathological changes will occur, which will start self-regulation mechanisms to reduce abnormalities and help the organism to better adapt to microgravity. However, these adaptive changes may also induce degradation or damage to physiological functions. This paper summarizes the physiological effects of microgravity on the human body from the aspects of skeletal and mineral metabolism, muscle structure and function, vestibular functions, cardiovascular function and pulmonary function, as well as expounds some commonly used ground-based space analogies. The paper will provide a reference for further study on the physiological effects of microgravity.
