Set the constriction to $8\mathrm{.}0$ mm$.$ c$.$ d$.$ e$.$ Does the speed of the platelet before it reaches the constriction increase, decrease, or not change? With the $8-$mm constriction, is the speed of the platelet in the constriction faster, slower, or the same as with the $2-$mm constriction? Assume that the blood vessel and the blockage are cylindrical $($circular cross$-$sectional area for both$).$ Measure the radius of the artery and the radius of the flow area where the blockage is$.$ Verify the equation of continuity to compare the $2-$mm and $8-$mm cases. Aout$=\_\_\_\_\_\_\_$ Now compare the $2-$mm and $8-$mm cases. f$.$ Ain$=\_\_\_\_\_\_\_$ What is the pressure inside of and outside the constriction $($use the white box to measure pressure$)?$ Pin$=\_\_\_\_\_\_\_$ g$.$ Pout$=\_\_\_\_\_\_\_$ Does the pressure decrease or increase in the region where the blockage is$?$
