homeostasis
hoh-mee-oh-STAY-siss
/ˌhoʊmioʊˈsteɪsɪs/
The tendency toward a relatively stable equilibrium between interdependent physiological processes.
Refers to active biological regulation (temperature, pH, hydration) keeping internal state steady despite outside changes.
The story behind the word. Coined in 1926 by American physiologist Walter Cannon, combining Greek 'homoios' (like, similar) and 'stasis' (a standing still). It captures how living systems remain remarkably stable internally despite chaotic external environments.
Word relationships
- equilibrium: Equilibrium can be physical or chemical balance, while homeostasis specifically involves self-regulating biological systems.
- stability: General state of remaining unchanging.
- imbalance: Lack of stability or equilibrium.
- dysregulation: Failure of biological control mechanisms.
Commonly confused with
- homeopathy: Homeopathy is a system of alternative medicine, whereas homeostasis is dynamic biological self-balancing.
Word family
- homeostatic (adjective): Relating to internal biological balance.
Collocations
- maintain homeostasis
- homeostasis regulation
- disrupt homeostasis
- cellular homeostasis
Example sentences
- "Sweating during hot weather helps the body maintain temperature homeostasis through evaporative cooling." Human Physiology
- "Insulin and glucagon act together to preserve blood glucose homeostasis after meals." Endocrinology
Memory hook
HOMEO (home) + STASIS (staying same) = Body keeping home cozy and stable. Homeostasis = Biological self-balancing.
When not to use
Do not confuse with static physical balance like a seesaw.
Fun facts
- Sweating when warm and shivering when cold are textbook homeostatic responses designed to keep your body temperature near 37°C.
