How does feedback mechanism help control body temperature?

The feedback mechanism, also known as feedback inhibition, is a stimulator that halts/induces particular proteins/enzymes from doing their job.





Example:


If there is high levels of insulin in the blood, the brain would signal the pancreas to stop producing insulin.





Likewise, when someone gets a fever, their body is fighting off the infection. Once the infection has been isolated/removed, the body decreases its energy (or focus) on the specific intruder. The brain signals for the WBC and T-Cells to stop attacking if nothing is remaining, and stops the production of WBC.


That's why you don't always have a fever, after having a fever (if that made any sense)





Let me know if that doesn't make sense.
