The velocity of the blood in the aorta is about 0.5 m/s, and the velocity of the blood in a capillary is about 0.001 m/s. We have only one aorta, with a diameter of 20 mm, but many capillaries in parallel, each with a diameter of 8 μm. Using vascular resistance approach estimate how many capillaries are typically open at any one time.
