Using Poisuille’s Law, calculate the flow rate in an artery of diameter 0.8 cm, length of 4 cm, with the coefficient of blood viscosity is 4*10-3 Pa-s at normal blood pressure of 120 mm-Hg. (6 points) How does this flow rate change upon a 20% occlusion of the artery? (4 points) What is usually the compensation process to hold the flow rate steady? (2 points)

3. 1/2 points | Previous Answers My Notes Smoking tobacco is bad for your circulatory health. In an attempt to maintain the blood's capacity to deliver oxygen, the body increases its red blood cell production, and this increases the viscosity of the blood. In addition, nicotine from tobacco causes arteries to constrict.

Plaque builds up on the walls of an artery decreasing its diameter from 1.16 cm to 0.70 cm. If the flow speed is 14.5 cm/s before reaching the region of plaque buildup, determine the following. (a) speed at which blood is traveling through the plaque-constricted region cm/s (b) pressure change within the plaque-constricted region. (Assume the density of blood is 1050 kg/m3. Be sure to include the appropriate sign with your answer.) Pa
