Unformatted text preview: EF. QUESTION 5 Consider a small artery of diameter 1.5 cm that simultaneously branches into three arterioles with diameters of 0.5 cm, 0.75 cm, and 1 cm. (45 total) A. If the blood flow through the small artery is 50 ml/min, at what velocity does blood flow through that artery? (10) Solution: , where Q = the flowrate and A = the cross- sectional area. . B. What is the flow rate (ml/min) of blood through the largest of the three arterioles? (15) Solution: To find out the flow rate in the arteriole, we need to figure out how the blood flow is split up when the artery branches. We can do this by comparing the resistances of the different arterioles. From Poiseuille’s Law, we know that resistance is inversely pro...
