WebNegative feedback, also known as negative loops, work to negate change and drive stability in systems. Again, negative feedback doesn’t mean a negative outcome, as it can stabilize systems. Certain mechanisms in the human body—such as those that regulate temperature of blood glucose levels—are great examples of negative feedback loops. WebSep 4, 2024 · When body temperature reaches normal range, it acts as negative feedback to stop the process. Feedback may be negative or positive. All the feedback mechanisms that maintain homeostasis use negative feedback. Biological examples of positive feedback are much less common.
