FU from destruction. The notion of "norm" is relative with respect to average state of the system in the given conditions. In case if conditions alter, the system's condition should change, too. Reaction is the action of the system aimed at producing the result of action necessary for its survival in response to external influence, ie the system's function. Reaction is always specific. Reaction may be: normal (normal reactivity), insufficient (hypo-reactivity), excessive (Hyper-reactivity), distorted (unexpected reaction occurs instead of the expected one). Normal reactivity (normal reaction) means that functional reserves of systems correspond to the force of external influence and the operating possibilities of control block allow to adjust (control) SFU so that the result of action precisely corresponds to the force of external influence. Hypo-reactivity of the system (pathological reaction) arises in cases when functional reserves of the given system of living organism are insufficient for the given force of external influence. Hypo-reactivity is always a pathological reaction. Hyper-reactivity of the system (normal or pathological reaction) is the one where the result of action of the system exceeds the target. Distorted reaction is a reaction of the system which mismatches its purpose. Pathology is the lack of correspondence of the systems 'resources to usual norms. Pathology includes other two important notions: pathological condition (defect) and pathological process (including vicious circle). Restoration is active influence on the system with a view to: liquidate or reduce excessive external influences destroying the Systemic Functional Units; liquidate or reduce destructive effects of vicious circle if it has arisen; strengthen the function of the affected (defective) subsystem, provided it does not lead to the activation of vicious circle; strengthen the function of systems conjugated with the defective one, provided it does not lead to strengthening the destructive effect of the vicious circle associated with the affected system or the development of vicious circles in other conjugated systems (does not lead to strengthening of the "domino principle"); replace the destroyed SFU with the operational ones. Any owner of the car knows that if something is broken in his/her car (as a result of excessive external influence) and the defect turns up, the transportation possibilities of its car sharply recede. If failing immediately repairing the car, the breakages would accrue catastrophically (vicious circle) because the domino principle will be activated. And to "cure" the car it is necessary to protect it from excessive external influences and to liquidate the defects.
