title: [Helical (spiral or swirling) blood flow in cardiovascular system].
abstract: In article covers theoretical preconditions for the hypothesis about helical (spiral or swirling) blood flow in cardiovascular system followed by its experimental corroboration. The role of the modern blood flow visualization methods--such as Color Doppler ultrasound and magnetic-resonance angiography--in registration and investigation of the regularities of the given phenomenon is described. The data describing the known parameters of helical blood flow--such as direction of the rotation and its quantitative parameters in large arteries--are given. The main hypotheses for flow screw mechanisms are considered from the point of view of cardiovascular system structural organization. Biological role of helical blood flow is discussed, in respect of which there are diametrically opposed points of view, which consider it as a physiological phenomenon on one side, and as a patogenetic factor of atherosclerosis development on the other.
