WebApr 14, 2024 · The negative feedback loop helps to balance homeostasis by recognizing there is a problem in the body and sending out the right response. The loop stays where it is at and sends out different “effectors” to do the work. Let’s take a look at how the feedback loop works. What Is a Negative Feedback Loop?
