The regulation of homeostasis in living organisms is mainly accomplished by feedback mechanisms. These mechanisms involve sensors that detect changes in internal conditions, such as temperature or pH, and send signals to the control center (usually the brain or endocrine system) to initiate appropriate responses. The responses may involve the activation of effectors, such as muscles or glands, to restore balance. Homeostasis is essential for maintaining a stable internal environment, which is crucial for overall health and survival.
