Abstract
In the present work the outcomes of mining of updated model of calculation of a circulatory system of the person taking into account a morphological feature of an organism are resulted. The computational scheme allows for features of branching of a main vascular bed, change of lengths and diameters of arteries in dependence on age and sex, and as a connecting circuit of arteries and veins of an internals. The model of calculation of a large circle of a circulation constructed on the establishment of the computational scheme of a circulatory system, algorithm of its calculation and difiniendums haemodynamic parameters is submitted. The computational Bernoulli´s relation utilized for the description of fields of a vascular bed is described: an aorta, artery, arterioles and capillaries. The set of equations for calculation of differences of pressure and consumption of a blood for the basic organs and tissues of an organism are adduced. The description of outcomes of primary researches executed on offered model is in summary adduced. Influencing a hydrostatic fluid column on pressure of a blood in fields of a vascular bed is investigated. Matching models of calculation is executed: disregarding of aorta-arterial field (AAF), with allowance for AAF, with allowance for AAF and arterioles. The check of veracity of the given model on an example of two tissues of an organism head and myocardium is conducted. The sensitivity and capabilities of offered model is routined.
