The following table describes approximate physical characteristics of the vessels in the circulatory system: Vena Aorta Arteries Arterioles Capillaries Venules Veins cava Diameter of a single 2 0.5 0.002 0.0009 0.003 0.5 3 vessel ( cm) Total cross- sectional area of all 3 20 500 4000 3000 80 7 vessels of given type in the body (cm) In an average arteriole, blood pressure drops from about 80 mmHg to about 30 mmHg. What is the approximate length of such an arteriole in centimeters? You may assume that the total blood flow rate entering the circulatory system from the aorta is about 5 L/min, and the viscosity of blood is around 2.5 103 Pa s.
