Which the model of homeostasis—or adverse feedback—cannot describe the consequences of consistently administered drugs in a satisfactory way was extensively mentioned in the previous paper (Peper 2004a).
Fig. 1 demonstrates a block diagram of the regulated adaptive process. The method produces a hypothetical material. Its regulation is disturbed by an exogenous compound of the same composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the procedure, the method regulator and an adaptive regulator. Once the exogenous substance changes the extent of your compound while in the bloodstream the adaptive regulator accurate for this disturbance by readjusting the output level of the method.

When an exogenous substance is taken orally and there won't be any environmental cues paired towards the drug getting, the compensatory mechanism will not be triggered when the administration with the drug is stopped and no reactions will take place (Peper et al.
