Multiple Choice

The ability of the body to repair and maintain itself to achieve a 'steady state' defines what term?

Maintaining a stable internal environment through regulatory processes defines homeostasis. The body keeps variables such as temperature, pH, glucose, and fluid balance within narrow ranges by sensing changes and triggering responses that counteract them. This steady-state maintenance relies on feedback systems, often negative feedback, to return deviations toward a set point. Anabolism and catabolism are metabolic processes—the former builds up molecules, the latter breaks them down for energy—while hemostasis refers to stopping blood loss after injury. Because homeostasis specifically describes the active maintenance of internal stability to achieve a steady state, it is the best term to describe the body's ability to repair and maintain itself.
