(a) As blood passes through the capillary bed in an organ,the capillaries join to form venules (small veins). If the bloodspeed increases by a factor of 4.00 and the total crosssectionalarea of the venules is 10.0 cm2 , what is the totalcross-sectional area of the capillaries feeding these venules?(b) How many capillaries are involved if their averagediameter is 10.0 μm ?
