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)

Below are typical values for blood flow through a coronary artery. Note that viscosity of the blood is not neglected. Density of blood, ρ = 1060 kg/m3 Viscosity of blood, ν = 0.004 Pa x s Flow rate, Q = 0.8 mL/s Length of artery, L = 3.5 cm Radius of artery, r = 0.2 cm For the same pressure drop, calculate the flow rate if the radius of the artery reduces by 30% its original value due to blockage?

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.
