Negative feedback loops play an important role in how many of the systems of the human body stay in control. A negative feedback loop, also known as an inhibitory loop, is a type of self-regulating system. In a negative feedback loop, increased output from the system inhibits future production by the system. In other words, the system controls how much product it makes by shutting down manufacturing when levels of output or the amount of accumulated product gets too high.
Negative feedback systems are responsible for many types of hormone regulation in the human body. They are good at maintaining relatively constant levels of output.
