Increased. All It Means A Deviation From The
increased. All it means a deviation from the law of a constancy of the internal environment, from the law which observance, as well as protection, is necessary for the sake of a life. However we know that owing to the cybernetic mechanism of regulation systems aspire to balance or to stability and order restoration. Therefore the question is quite reasonable: how can during all situations while there is "a meeting of a cat with a dog", to exist infringement of the internal environment of an organism? Really, if concentration in blood of a working hormone raises, for example it, according to the mechanism of a negative feedback, should brake allocation of the regulator, in this case a hormone , and allocation , not stimulated , should decrease to norm - to the limits protected by the law of a constancy. But after all it does not occur, and level in blood in stress remains raised, creating thereby the mechanism protection. In what here business? For each hormone-regulator there is a working factor which at concentration increase in blood causes suppression of activity of a regulator.
