Phenomenon of concentrical spiral separation of microparticles in laminar vortical blood flow.
1. Previously unknown phenomenon of a stable ordered laminar vortical blood flow of opposite direction has been discovered in the systemic and pulmonary circulations consisting in the fact that in the circulation system there exists a rotative, twisted, spiral-like blood movement due to (a) special organization of intracavitary architectonics of heart and blood vessels in the form of funnel-like cavities with tangential inflow into the heart, outflow from the heart and blood vessel branching, (b) twisting character of contraction of spiral-oriented muscular elements creating the ejection effect of the vortical blood jet. 2. Previously unknown phenomenon of concentrical spiral separation of blood microparticles has been discovered consisting in the fact that in moving blood there exists a layered distribution of microparticles on flow radius according to their size and mass due tot the stable ordered laminar vortical blood flow of opposite direction in the systemic and pulmonary circulations, the largest and heaviest microparticles constituting the axial nucleus of the flow and the smallest and lightest microparticles constituting parietal layers.
