Fig. 1 displays a block diagram of the regulated adaptive procedure. The process provides a hypothetical compound. Its regulation is disturbed by an exogenous compound of exactly the same composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the process, the method regulator and an adaptive regulator. If the exogenous compound alterations the level in the material from the bloodstream the adaptive regulator suitable for this disturbance by readjusting the output degree of the procedure.
