Calculate the average speed of the blood in the aorta if the flow rate is 5.0 L/min. Please cite any assumptions. This same total amount of blood eventually flows through the collective network of capillaries. When the rate f blood flow in the aorta is 5.0 L/min, the speed of the blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0µm, calculate the number of capillaries in the blood circlatory system. Show work.
