a. speed*area=rate
speed= 9.6e-5/(PI*.004^2) cm/sec
b. same formula, except rate is not 1/8800. Notice diameter is in meters, suggest change to cm first.
A typical arteriole has a diameter of 0.080 mm and carries blood at the rate of 9.6×10−5cm3/s. \
a. What is the speed of the blood in an arteriole?
b. Suppose an arteriole branches into 8800 capillaries, each with a diameter of 6.0×10−6m.What is the blood speed in the capillaries? (The low speed in capillaries is beneficial; it promotes the diffusion of materials to and from the blood.
