example of thermostat to explain homeostasis?

Answer 1

A thermostat's job is to keep a house at an even temperature. It's cold right now, so let's think of a furnace with a thermostat. The furnace cycles on and off as needed to keep the house at a certain temperature. When the room temperatue drops a little, the furnace kicks back on to warm it up again.

A warm-blooded, endothermic animal like ourselves does the same thing. Our bodies generate enough heat to keep our body temperature stable. Only in a living thing, this keeping everything in balance is called homeostasis. We burn more food in cellular respiration and shiver to keep body temperature in the same range.

Likewise, a thermostat can control the air conditioner to keep the house at an even temperature. Our bodies perspire and dilate the blood vessels near the skin to get rid of excess heat. That cools us off and keeps us at an even temp. This is homeostasis.

Answer 2

Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms. The term was coined in 1932 by Walter Bradford Cannon from the Greek homoios (same, like, resembling) and stasis (to stand, posture).

Our bodies have an internal thermostat which regulates our temperature to keep it constant.

Our homes have a thermostat, which turns on and off the heater or air conditioning, in order to maintain the temperature inside at a constant, comfortable temperature for us.
