Homeostasis is the ability of living organisms to maintain a stable, relatively constant internal environment (like temperature, pH, water balance, blood sugar) despite changes in external conditions, ensuring cells and systems function optimally for survival. It’s a dynamic process involving feedback loops, primarily negative feedback, where the body detects deviations and triggers responses (like sweating to cool down or shivering to warm up) to bring conditions back to a set range, preventing disease and maintaining life.
