What Is Biological Homeostasis?

Homeostasis, also known as "homeostasis" and "internal environment stability", refers to the tendency and mechanism of an organism to maintain a relatively stable internal environment when the external environment changes significantly.

Homeostasis, also known as "homeostasis" and "internal environment stability", refer to the tendency and mechanism of an organism to maintain a relatively stable internal environment when the external environment changes dramatically.

Homeostasis is critical to the survival of an organism. A large number of basic survival motives, such as hunger and thirst, are used to adjust the state of the organism to adapt to the environment. For example, the normal body temperature of the human body must be maintained at about 37 degrees, and the up-and-down fluctuation does not exceed 1 degree. If the deviation from the normal body temperature for a long time exceeds a certain limit, people will be destroyed due to various biochemical balances in the body and unable to perform metabolism and die. The amount of water, sugar, fat, amino acids, etc. inside and outside the organism's cells also needs to be maintained at a certain level by the homeostasis mechanism. ^[1]

Homeostasis is a regulating system, including the corresponding variables that need to be adjusted, the sensors that detect the variable, the normal value of the variable in the body, a comparator that compares the actual value of the variable with the ideal value, and makes a comparison based on Regulation of five aspects. Corresponding variables can be adjusted through automatic physiological responses (such as sweat secretion to reduce body temperature) and intentional behavioral responses (such as dressing or maintaining or gaining heat in warm places). ^[1]
