Study Notes
Homeostasis
- Homeostasis is the ability of the body to maintain a stable internal environment despite changes in the external environment.
- It is the regulation of the body's internal conditions, such as temperature, pH, and the concentration of essential nutrients, to maintain a stable and constant environment.
Maintenance of Homeostasis
- Homeostasis is maintained by the nervous system and the endocrine system, which work together to regulate the body's internal conditions.
Regulation of Homeostasis
- The body's internal conditions, such as temperature, blood sugar levels, and blood pressure, are kept within narrow limits to maintain homeostasis.
- This is achieved through a negative feedback mechanism, where any changes in the internal environment trigger a response to return the conditions to their normal range.
Test your knowledge on homeostasis, the state of equilibrium in the body. Explore how the body naturally maintains this balance through adaptive responses, ensuring that body fluids and electrolytes are kept within narrow limits.
