生理

生理 refers to the study of the functions and processes of living systems, particularly in humans. It is often used in scientific or medical contexts to describe the normal functioning of the body.

The character 生 (shēng) means 'life' or 'to be born,' while 理 (lǐ) means 'principle' or 'law.' Together, they form a term that literally translates to 'the principles of life,' emphasizing the natural processes that sustain living organisms.

生理 is commonly used in academic and health-related discussions. In daily conversation, it may appear in phrases like 生理需求 (physiological needs), referring to basic human requirements such as food, water, and sleep. Understanding this term can help learners grasp more complex scientific vocabulary in Chinese.
