allostasis

What are the similarities and differences between homeostasis and allostasis

[REBORN]

Both maintain a stable physiological environment for the body however allostasis does this by changing.

[che0106]

Allostasis revises and extends biological construct of homeostasis
Homeostasis is the body’s ability to maintain a stable physiological environment by keeping certain bodily conditions constant (body temp, blood oxygen level)
Maintained within a narrow range of values (‘set points’)

[leona0123]

Allostasis helps the body to achieve stability by changing (e.g. increases heart rate to allow the body to function properly during times of high activity). It is like a thermostat in a centrally heated home that constantly adjusts to maintain a relatively stable temperature.
Homeostasis helps the body to achieve stability through staying the same (e.g. maintains core body temperature and blood oxygen levels).
