Abstract

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.

摘要

该文章称,心脏左心室的收缩会产生血液的旋转(湍流)运动,并在主动脉中持续存在。在大动脉和小动脉的壁以及小动脉壁中,肌细胞呈螺旋状排列。尽管它们的雷诺数相当小,但它们的收缩仍能维持小直径血管中的湍流血液流动。作者认为,在对动脉中流动的血液进行数学分析时,有必要考虑到动脉血管壁会对血流产生积极影响。
