The term for the body's ability to maintain stable physical and chemical conditions is called homeostasis. This process involves various physiological mechanisms that work together to regulate factors such as temperature, pH levels, and electrolyte balance. Homeostasis is crucial for the body to function effectively, as any significant deviation from these stable conditions can lead to illness or dysfunction. The body continually adjusts its systems to respond to external and internal changes, ensuring optimal performance and health. Achieving homeostasis is key to maintaining overall well-being.
