The average density of blood is p=1.06 X 10^3 kg/m^3. If you donate 1.00 pts of blood to the Red Cross, what mass of blood have you donated, in grams? (1 pt=0.437 L, 1 L=1000 cm^3, p=m/V

Blood Speed in an Arteriole: A typical arteriole has a diameter of0.030 mm and carries blood at the rate of 5.5 x 10 ^ -6cm^3/s.

A.) What is the speed of the blood in an arteriole?

V= ___ cm/s

B.) Suppose an arteriole branches into 340 capillaries, each with adiameter of 4.0 x 10 ^-6 m. What is the blood speed in thecapillaries? (The low speed in capillaries is beneficial; itpromotes the diffusion of materials to and from the blood.)

v = ____ cm/s

Question 3
Smoking tobacco is bad for your circulatory health. In an attemptto maintain the blood's capacity to deliver oxygen, the bodyincreases its red blood cell production, and this increases theviscosity of the blood. In addition, nicotine from tobacco causesarteries to constrict. For a nonsmoker, with blood viscosity of2.5x10^-3 Pa*s, normal blood flow requires a pressure difference of8.0 mm of Hg between the two ends of an artery. If this person wereto smoke regularly, his blood viscosity would increase to 2.7x10^-3 Pa*s, and the arterial diameter would constrict to 90% ofits normal value. What pressure difference would be needed tomaintain the same blood flow?
