Study Notes
Homeostasis in Living Organisms
- Homeostasis is the regulation of internal functions to maintain stability despite external changes.
- It allows organisms to adapt to varying environmental conditions and keep core physiological processes functioning optimally.
- The human body typically maintains a temperature between 36.1°C and 37.2°C.
- When exposed to cold environments, the body initiates shivering to generate heat and maintain internal temperature.
- In hot conditions, the body activates sweating to cool down through evaporation.
