As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). 1. If the blood speed increases by a factor of 4.00 as it enters the venules, which have a total cross-sectional area 9.5 cm2, what is the total cross-sectional area, in square centimeters, of the capillaries feeding these venules?  A2=(in cm^2) 2. How many capillaries are involved if their average diameter is 7.5 μm? N=
