Homeostasis ran mainly by negative feedback, a term used to describe the process of keeping a certain system at a set point. No matter what way a system is going, either up or down, a force is applied in the opposite direction in order to bring it back to it's set point. One common example of negative feedback would be body temperature. Humans deal with this system every day. The common set point for most human's body temperatures should be 98.6 degrees. If the core body temperature in a human goes even a few degrees in either direction, the person will most likely have to go to a doctor to get checked out. In an attempt to keep us from making regular doctor trips, our body is constantly working to keep our temperature at that set point of 98.6 degrees. Another example of negative feedback would be dehydration. If a person gets dehydrated, their body will send a message letting their brain know that they need water badly. The person will then drink lots of water and eventually, their fluid balance will be back to normal. There are multiple examples of how our body maintains homeostasis and each of them are vital to our survival.
