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?

In the normal region of an artery, the blood pressure is 100 mm Hg and the flow speed is 0.12m/s. By what percentage would the pressure drop in this artery as the blood (density 1.05 x 10^3 kg/m^3) enters a region that has been narrowed by atherosclerotic plaque to a cross-sectional area one fifth of normal? Assume there is no change in elevation of artery and viscosity is negligible

An artery has a narrow section in which the blood speed is 7.5 cm/s. In the wider part of the artery, the blood speed is 5.0 cm/s. The blood pressure in the wider part is 16 kPa. Calculate the blood pressure (in kPa) in the narrow section, assuming that the height change is zero. The density of blood is 1060 kg/m3. The gravitational field is g = 9.8 N/kg.

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.
