Homework Help: Flow of blood

  1. Nov 22, 2004 #1
    (a) An arteriole has a diameter of 0.029 mm and carries blood at the rate of 6.2 10-6 cm^3/s.
    What is the speed of the blood in the arteriole?

    (b) Suppose the arteriole branches into 340 capillaries, each with a diameter of 4.0 10-6 m. What is the blood speed in the capillaries? (The low speed in capillaries promotes the diffusion of materials to and from the blood.)
