Its regulation is disturbed by an exogenous compound of precisely the same composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the procedure, the process regulator and an adaptive regulator. In the event the exogenous substance variations the extent of the material from the bloodstream the adaptive regulator correct for this disturbance by readjusting the output level of the process.
