This paper is a continuation of our first paper «”onal model” of description of homeostasisussed some general regularities of the organism functioning connected directly with maintenance of homeostasis. It might seem that consideration of such general issues could have been only of theoretical interest; however, for the recent years, a trend has been formed in direction of cholistic physiology and medicine when there are considered first of all the organism functioning regularities responsible for maintenance of its integrity in norm and in pathology. A particular attention in the present paper is paid to consideration of multifunctional possibilities of organs and functional blocks. In our opinion, such analysis can promote solution of general problems of physiology and medicine and provides a possibility to better understand organization of processes in the organism throughout the lifespan as well as can help in elucidation of causes of some chronic diseases.
In this work, peculiarities of functioning of living organisms, which are connected with the function of maintenance of homeostasis, are discussed. Many authors wrote about homeostasis, however from position, as a rule, of some concrete disciplines; this prevented from combining the already existing facts and concepts in terms of the common approach explaining physiological processes occurring in the organism as the integral system. Specifically, the insufficient attention, in our opinion, was paid to homeorhesis and analysis of such aspect of maintenance of homeostasis as use by the organism of multifunctional possibilities of organs and other structural-functional components. In this work, an attempt is made at compensating this gap: a new, zonal model of description of homeostasis is proposed, the already known regularities of functioning of living systems are considered, and their list is supplemented. In our opinion, this can promote solution of general problems of physiology and medicine and allows better understanding of organization of processes in living organisms. Besides, in terms of our approach, it is easier to explain some physiology changes occurring in the process of evolution.
