There are two kinds: one that turns off a reaction and one that adds to it. Negative feedback will stop a reaction when it is complete and will not allow it to continue to run. Most of our body systems work in this manner. It is some like filling a washing machine. It will turn off when full and begin to wash. The opposite is positive feedback, that washer will over flow. One of the best examples of positive feedback is the clotting mechanism.

I'm not sure exactly what is in it [sorry, I'm too lazy :*(], but an adrenaline feedback loop diagram is, well, a diagram showing the feedback loop that adrenaline uses to signal itself to pump adrenalin through the body.
positive feedback loop because cause increases the effect. thank you very much!
A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
Feedback oscillators have a closed loop gain of
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
Feedback Loop - 2008 is rated/received certificates of: UK:PG
A: DEFINITELY NOT Open loop is defined as no feedback. any kind of negative feedback will reduce the gain

- temperature - negative feedback loop - positive feedback loop - water balance
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
