GENERAL HISTOLOGY

Detailed explanation-1: -Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Detailed explanation-2: -The type of signal used in a heating system is called negative feedback because the system is turned off by the condition it produces.

Detailed explanation-3: -A negative feedback is a self-regulatory system in which it feeds back to the input a part of a system’s output so as to reverse the direction of change of the output. The process reduces the output of a system in order to stabilize or re-establish internal equilibrium.

Detailed explanation-4: -Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state.
