Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions. This involves regulatory mechanisms that control variables like body temperature, blood glucose levels, and pH. Maintaining homeostasis is crucial for the survival and proper functioning of cells and the organism as a whole. Think of it like your body's thermostat, constantly working to keep everything balanced! 🌡️
