The term for the ability of an organism to maintain stable internal conditions is known as homeostasis. This regulatory process allows organisms to manage their internal environment, ensuring optimal conditions for survival despite external fluctuations. Homeostasis involves various physiological mechanisms, including temperature regulation, pH balance, and fluid levels. It is essential in maintaining cellular function and overall health. Disruption in homeostasis can lead to disease or dysfunction. Understanding this concept is crucial in fields such as physiology and medicine, providing insights into health and disease management.
