Effects of tobacco UT 1 point Smoking tobacco is bad for your circulatory health. In an attempt to maintain the Suppose that the effect of the nicotine caused the diameter of a smoker's arteries blood's capacity to deliver oxygen, the body increases its red blood cell production, to constrict by 12%. If normal blood flow between the two ends of a certain artery and this increases the viscosity of the blood. In addition, nicotine from tobacco requires a pressure difference of 8.5 mm of Hg, what pressure difference (in mm of causes arteries to constrict. Hg) would be required to maintain the same blood flow rate for the smoker? For a non-smoker, blood viscosity is typically about 2.50 x 10-3 Pa.s. Regular Type your answer.. smoking could cause the blood viscosity to increase to 2.80 x 10-3 Pa.s -- an increase of 12%. Su
