Negative/ Positive Feedback Loops

Feedback means that the results of a process feed back into the system to change the rate of that process.

 2 Feedback Loops

-Negative Feedback Loops are systems that respond to a change by returning to its original state, or at least by decreasing the rate at which the change is occurring.

- Positive Feedback Loops are systems that amplify changes, whereas negative feedback loops resist changes.

Negative  feedback loops usually predominate.

Example of Negative Feedback is the body's Insulin Response
