Homeostasis

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions. This balance ensures that essential functions, like temperature, pH, and hydration levels, stay within a narrow range necessary for survival. For example, when you exercise, your body sweats to cool down and regulates your heart rate to support increased activity. Homeostasis is crucial for overall health, as it helps organisms adapt to their surroundings and respond to stressors, ensuring that systems operate efficiently and effectively.
