In humans, blood flows from the heart into the aorta, from whichitpasses into the major arteries. These branch into thesmallarteries (arterioles), which in turn branch into myriads oftinycapillaries, see the figure. The blood returns to the heart viatheveins. The radius of the aorta is 1.0 cm and the bloodpassingthrough it has a speed of about 32 cm/s. Atypical capillaryhas a radius of about 4 Ã 10-4cm, and blood flowsthrough it at a speed of about 5 Ã10-4 m/s. Calculatethe average speed of blood flow inthe major arteries of the bodywhich have a total cross-sectionalarea of about 2.1 cm2.
