In this video, we look at negative feedback and positive feedback. First we explore negative feedback, looking at the key features of a negative feedback system. This includes the stimulus, receptor, coordinator, effector and response. We see why negative feedback is an important part of homeostasis.

We then look at what is meant by positive feedback and compare this with negative feedback.
