Key Concepts

Homeostasis

Homeostasis is the concept of maintaining a stable internal environment by regulating variables such as temperature, pH, and other physiological parameters within narrow limits. It relies on negative feedback mechanisms to correct deviations from a set point, ensuring that the organism's internal conditions remain constant despite external changes.

Allostasis

Allostasis expands on the idea of homeostasis by emphasizing the body’s ability to achieve stability through change. It involves active and dynamic regulatory processes that not only respond to current disturbances but also anticipate future demands, adjusting set points and engaging various physiological systems. This concept recognizes that the organism adapts to stressors and varying environmental conditions in a predictive, flexible manner.
