Homeostasis is a word that you probably came across once or twice back in biology class, but do you remember what it means? Or how to use it in a sentence? Not to worry — we’re here to help. 

In this guide, we’re exploring the term homeostasis to uncover its definition, origin, and more. If you’ve ever wondered about the meaning behind homeostasis, keep reading! 

What Is the Definition of Homeostasis?

Homeostasis refers to a cell’s base state if everything that regulates it is working correctly. It’s often called a cell’s “home state” in biology.

Though the theory of homeostasis was first introduced in 1865 by the French physiologist Claude Bernard, it was not until close to 100 years later that homeostasis was first used as a term. In the year 1926, Walter Bradford Cannon combined two Ancient Greek words to make homeostasis: ὅμοιος and ἵστημι, meaning “similar or standing still.”

Homeostasis does not stray from the range of the body’s ideal conditions. This maintenance of these homeostatic conditions must be maintained by all living organisms to survive — not just us humans. 

Disease is the leading cause of the disruption of homeostatic mechanisms; however, one can work with nature and re-establish these ideal homoeostatic conditions with effective therapy.

How Does the Body Maintain Homeostasis?

A great example of how our body maintains homeostasis is something that surely our grandfathers or dads have yelled at us about once in our lives — thermostats. For instance, once you set the thermostat in your house to your ideal temperature, the furnace and air conditioner work together to maintain this ideal, preset temperature.

Our bodies have set points for various states — including hunger, thirst, sleep, temperature, and weight. Even if only slightly too large or perhaps just a hair too small, homeostasis will begin to correct any action immediately if any of these setpoints are off in any direction. 

Below you will find a list of the primary components of homeostasis in our bodies:

  • Stimulus — This refers to something that causes part of the body to react, usually referring to a change in the environment that causes the body to be unbalanced.
  • Receptor — A receptor’s sole purpose is to inform the control unit of any stimulus.
  • Control Unit — Once the information is received by the control unit, it then communicates with the needed parts of the body to begin the process of homeostasis and bring the body back into balance.
  • Effector — Acts on any changes the control unit has communicated needs to be done.

There are also varying types of homeostatic regulation, such as thermoregulation, osmoregulation, and chemical regulation. Behavioral responses and psychological responses are involved regarding homeostasis.

A simple example of homeostasis is the body’s ability to maintain a steady temperature.

In Conclusion

We hope we were able to convey to all of you reading at home that homeostasis refers to a state of balance — a  balance among all the various body systems that one may need daily to function correctly and survive.

If your body is in a state of balance or, more aptly, homeostasis, body levels of blood sugar, energy, temperature, oxygen, and protein (just to name a few) are constantly adjusted in response to all sorts of changes.
