(a) Calculate the average blood velocity in the major arties given that the aorta has a radius of 1.0 cm, the blood velocity is 30 cm/s in the aorta, and the total cross-sectional area of the major arties is 20 cm2 (b) What is the total flow rate? (c) On the assumption that all the blood in the circulatory system goes through the capillaries, and given that the average velocity of the blood in the capillaries is 0.03 cm/s, what is the total cross-sectional area of the capillaries?
