Homeostasis

Definition

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions.

Scientific / Technical Definition

Homeostasis refers to the dynamic process that enables organisms to regulate their internal conditions, such as temperature, pH, and energy balance, within certain physiological limits. It involves various feedback mechanisms that counteract deviations from a set point, allowing the organism to function optimally.

Benefits

• Maintains stable body temperature
• Regulates blood sugar levels
• Balances pH levels in the body
• Controls the internal environment to support survival

Examples

• Thermoregulation to maintain body temperature
• Blood sugar regulation through insulin and glucagon
• The kidney's role in maintaining electrolyte balance

Additional Information

• Importance: Homeostasis is critical for the survival and proper functioning of living organisms, as it ensures that physiological processes occur under optimal conditions.
