The article claims that contractions of the cardiac left ventricle produce a whirling (turbulent) movement of blood that is maintained in the aorta. In the walls of large and small arteries, as well as in the arteriolar walls, myocytes have a spiral arrangement. Their contraction maintains the turbulent blood stream in the vessels with a small diameter, in spite of the fact that the Reinolds' number for them is rather small. The author considers that while making a mathematical analysis of the blood flowing in the arteries, it is necessary to take into account that the walls of the arterial vessels actively influence the blood stream.
