Coevolution of physiological systems

Coevolution is the interaction in the process of evolution of different species that are closely related biologically but do not exchange genetic information. In this paper, we address the problem of coevolution of the whole organism's physiological systems as a process of the interrelated development of structure and function as well as their regulatory systems during the formation of living organisms. We consider the coevolution of osmoregulation and the nitrogen metabolism type, systemic and individual coevolutionary strategies of cell volume regulation in poikiloosmotic and homoiosmotic animals, coevolution of effectory organs and endocrine factors in the development of water-salt homeostasis, co-involvement of neurohypophyseal nonapeptides and glucagon-like peptide-1 in the regulation of the renal function aimed at stabilizing physico-chemical parameters of extracellular fluids which make up the internal environment of the organism.
