Problem 1. (Effects of tobacco) 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. For a nonsmoker, with blood viscosity of 2.5 x 10 Pa . s, normal blood flow requires a pressure difference of 8.0 mm Hg between the two ends of a certain artery. If this person were to smoke regularly, their blood viscosity would increase to 2.8 x 10" Pa . s, and the diameter of their artery would constrict by 10 %. A. Assuming that the pressure difference between the two ends of the artery does NOT change (not necessarily a good assumption), how would the blood flow be affected by the increase in viscosity of the blood and the decrease in the diameter of the artery? Select all that apply. a. The change in viscosity would decrease the blood flow. b. The change in viscosity would increase the blood flow. c. The change in viscosity would not change the blood flow. d. The change in diameter would decrease the blood flow. e. The change in diameter would increase the blood flow. f. The change in diameter would not change the blood flow
