Modelling the Dynamics of the Interaction of Physiological Systems


U.P. Muha, S.V. Ivantcov

The main purpose of the study in this article is the mathematical modeling of processes in the two interacting physiological systems of the human body (cardiovascular system and maintain a normal pressure), taking into account their interaction. The mechanical properties of these systems, their behavior in the presence of pathological changes and external influences, also the transport processes of substances. The description of the movement of blood in the circulatory system was based on the laws of mass and momentum con-servation. Vessels are quite extensive in comparison with its transverse size (diameter), which allowed them to use the approxima-tion of the mathematical description. From the review of the process flow models of physiological systems, we obtain a set of equations for computer simulation to examine the dynamics of interaction between these systems. Also presents a theoretical graph of the interaction of physiological systems in the diagram PV, as a cycle, which denotes many specific areas and points on the graph.
