Homeostasis
Shrink Definition
Homeostasis is the biological process through which the body maintains relatively stable internal conditions despite continual changes in the external environment. Temperature, blood pressure, blood glucose, hydration, oxygen levels, and countless other physiological variables are continuously regulated through homeostatic systems. Psychological functioning depends upon biological stability.
Plain language
