Homeostasis is the property of an organism to regulate its internal environment in response to external stimuli in order to maintain a consistent state. Homeostasis can apply to temperature, pH, heart rate, etc. Homeostasis is a regulatory mechanism that is necessary for limiting sensitivity of changes in environment. An example of its application would be one jumping into a cold pool and originally shivering, but then becoming less aware of the cold water. Without homeostasis, we would only be able to function effectively at a naturally set environmental standard. The pool in the image above is an example of where homeostasis is often utilized.
