Abstract/OtherAbstract:
The aim of the present paper is to illustrate schematically by a non-equal arm lever system the mechanisms that maintain the homeostasis of reactive oxygen species, glucose, mean arterial pressure and electrolytes. All regulating factors that increase the values of each physiological parameter are placed on the same arm of the lever system. The regulating factors that decrease this value are placed on the other arm of the lever. In this way the two types of factors interact with one another and maintain the lever system in a dynamic equilibrium, i.e., contribute to keeping the homeostasis. Illustrating the maintenance of homeostasis by a non-equal arm lever system gives the opportunity to express the quickness, flexibility, stability and effectiveness of physiological regulations.
