Homeostasis:- Homeostasis is the maintenance of a stable internal environment within an organism despite changes in the external environment. It is a crucial process for the survival of living organisms and involves the regulation of many internal variables such as temperature, pH, blood sugar, and water balance.
Homeostasis is achieved through a series of feedback mechanisms that detect changes in the internal environment and activate responses to restore balance. These mechanisms are generally controlled by the nervous and endocrine systems, which send signals to various organs and tissues to adjust their activity levels in response to changing conditions.
For example, when the body temperature rises, the thermoregulatory center in the brain sends signals to sweat glands to produce sweat, which cools the body by evaporating from the skin surface. Conversely, when the body temperature drops, the same center signals to muscles to shiver, generating heat to warm up the body.
In summary, homeostasis is the maintenance of a stable internal environment, and it is essential for the proper functioning of all living organisms.
