BIO (a) Calculate the mass flow rate (in grams per second)
of blood (p = 1.0 g/cm³) in an aorta with a cross-sectional
area of 2.0 cm² if the flow speed is 40. cm/s. (b) Assume that
the aorta branches to form a large number of capillaries with
a combined cross-sectional area of 3.0 × 10* cm². What is the
|flow speed in the capillaries?
