Homeostasis.. What is it?

Homeostasis. What is it? Homeostasis is the ability to maintain relatively stable internal conditions as the outside world changes. For instance, when were running, what is exactly happening to our bodies? So many things are happening all at once, it is hard to keep up. All the different levels, including glucose and temperature levels, that we have in our bodies move up and down when were working out or running. And although we never think about it, every organ in our body plays a specific role in order to keep us functioning when were moving or burning calories. Another thing that has its role to be controlled as much as possible is body temperature. When we work our bodies, we have to be careful and make sure we are taking care of our bodies as much as possible. Two control mechanisms of homeostasis is negative and positive feedback. Negative feedback is when the variable changes in a direction opposite to that of the initial change. In this case, when were done running, negative feedback plays its role and puts our body temperature back to where its supposed to be. In positive feedback, the response is accelerated in the same direction as the initial disturbance.
