PASSAGE
Homeostasis is a fundamental concept in biology, referring to the ability of an organism or system to maintain a stable, constant internal environment. This self-regulating process allows biological systems to remain in equilibrium while adjusting to changing external conditions. For example, the human body maintains a core temperature of approximately 37°C, regardless of whether the external temperature is hot or cold. When the body gets too warm, it sweats to cool down; when it gets too cold, it shivers to generate heat. These physiological responses are mechanisms to restore balance and ensure that cells can function optimally.
