Explanation

Homeostasis maintains stable internal conditions despite external changes. Examples: body temperature (37°C), blood glucose levels, water balance, pH. Negative feedback loops correct deviations from set point.

Temperature regulation: if too hot, blood vessels dilate (release heat), sweating increases. If too cold, vessels constrict (retain heat), shivering generates heat. Hypothalamus controls this.

Failure of homeostasis causes disease. Diabetes: cannot regulate blood glucose. Hypothermia/hyperthermia: temperature regulation fails. Understanding homeostasis helps understand many health conditions.
