When acid poisoning is handled with milk of magnesia, the alkaline action of milk of magnesia neutralizes the consequences of acid poisoning.
Fig. 1 shows a block diagram of a regulated adaptive process. The process makes a hypothetical compound. Its regulation is disturbed by an exogenous compound of a similar composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the process, the process regulator and an adaptive regulator. In the event the exogenous material improvements the level from the substance from the bloodstream the adaptive regulator appropriate for this disturbance by readjusting the output amount of the process.
The hypothesis underlying homeostasis—procedures are held at a steady state by opinions—has popular guidance. Nevertheless, although feed-back can assist to maintain a system at a preferred stage, the open up loop acquire of physiological processes is quite small (Peper 2004b) and its outcome in dynamic varieties of regulation will always be minimal.
An individual's height and bodyweight are linked by a straight line, which intersects the area space column.
