The effector receives the output and results in an appropriate change to maintain the variable factor within its limit.Based on the incoming signals, the control center determines if an adjustment is needed and sends the signal to the effector.The detector or sensor receives the input and integrates the incoming information in order to transmit it to the control center.The control center is the ‘brain’ of the system that determines the extremes within which the variable factor should lie.The feedback mechanism consists of three distinct components control center, detector, and effector.The most important function of the feedback mechanism in any system is to bring the state of the body into a stable state.In living systems, feedback mechanisms or feedback loops works to bring the body towards homeostasis by either amplifying a specific biological pathway or function or by inhibiting it.The concept of feedback mechanism was initially introduced in cybernetics to describe the ability of a control system to modify its output as a response to the input.

It is designated negative if the activation of a component leads to the deactivation of another. The interaction between the components can be designated as positive when the activation of a component leads to the activation of another.The biochemical control system in living beings is composed of various components like molecules, genes, and regulatory interactions of such components.The feedback mechanism is activated as a result of the change in the system that triggers an output.The feedback mechanism in the living system occurs in the form of a loop which assists in the maintenance of homeostasis.These mechanisms are also found in nature in different ecosystems and animal groups.The feedback mechanism is the physiological regulatory system in a living body that works to return the body to the normal internal state or homeostasis.
