The term for the body’s ability to maintain a stable internal environment is homeostasis. Homeostasis involves various physiological processes that regulate body temperature, fluid balance, pH levels, and other critical variables necessary for maintaining health and proper function. The body employs various mechanisms, including hormonal regulation and nervous system responses, to keep these parameters within specific ranges. Disruption of homeostasis can lead to health issues and affect bodily functions, emphasizing the importance of maintaining a balanced internal state for overall well-being.
