Coronary arteries have complicated branch and complicated curvature, and it is known as a part whose symptoms arteriosclerosis tends to show together with a main artery and a head artery. Moreover, in order to show the complicated action that a blood vessel is crushed or curvature changes, in connection with the pulsation of the heart, it is suggested that the shearing stress concerning a blood vessel wall becomes weak, or tends to become turbulent flow nature, and acts on arteriosclerosis. Then, we created a realistic model of magnified scale for coronary artery, and measured the flow velocity in a pipe using LDV. And we asked for the shearing stress applied to a blood vessel wall from the measured flow velocity in a pipe, and clarified influence which branch and curvature have on wall shearing stress.
