PHENOMENON OF CONCENTRICAL SPIRAL SEPARATION OF MICROPARTICLES IN LAMINAR VORTICAL BLOOD-FLOW

1. Previously unknown phenomenon of a stable ordered laminar vortical blood now of opposite direction has been discoreved in the systemic an d pulmonary circulations consisting in the fact that in the circulatio n system there exists a rotative, twisted, spiral-like blood movement due to (a) special organization of intracavitary architectonics of hea rt and blood vessels in the form of funnel-like cavities with tangenti al inflow into the heart, outflow from the heart and blood vessel bran ching, (b) twisting character of contraction of spiral-oriented muscul ar elements creating the ejection effect of the vortical blood jet. 2. Previously unknown phenomenon of concentrical spiral separation of bl ood 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 seze and mass due tot the stable ordere d laminar vortical blood flow of opposite direction in the systemic an d pulmonary circulations, the largest and heaviest microparticles cons tituting the axial nucleus of the flow and the smallest and lightest m icroparticles constituting parietal layers.
