The aorta carries blood away from the heart at a speed of about 35 cm/s and has a radius of approximately 1.2 cm. The aorta branches eventually into a large number of tiny capillaries that distribute the blood to the various body organs. In a capillary, the blood speed is approximately 0.080 cm/s, and the radius is about 6.8 x 10^-4 cm. Required:
Treat the blood as an incompressible fluid, and use these data to determine the approximate number of capillaries in the human body.
