What is Homeostasis?
Homeostasis is the theory that our body's internal environment stays more or less the same when the environment outside of our body, changes.
Why is it important that our body is able to maintain a stable internal environment?
Well to put it simply, our body needs a stable internal environment so that our organs continue to function and we can continue to live.
To help understand this theory a little better, lets think of changes in weather and how our body may respond to these changes and what would happen if it didn't.
