Vafter b. What is the platelet's speed while it passes through the constriction? constriction 10 A 13 MacBook Prowe" a a o a v a\" a Q _u. ._I-. Set the constriction to 8.l' c. Does the speed of the platelet before it reaches the constriction increase, decrease, or not change? d. With the 8-mm constriction. is the speed of the platelet in the constriction faster, slower, or the same as with the 2mm constriction? e. 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=____.__ in=_ I Memmewouwnesomas me" e e e a v a\" as Q Now compare the 2-mm and 8-mm cases. f.

Worksheet for Exploration 15.1: Blood Flow and the Continuity Equation Time: Blood flows from left to right in an artery 195 with a partial blockage. A blood platelet is shown moving through the artery. How does the size of the constriction Blood Flow (variable from 1 mm to 8 mm from each wall) affect the speed of the blood flow? Restart. Assume an ideal fluid (position is given in millimeters and pressure is given in torr = mm of Hg). We can use the continuity equation and Bernoulli's equation to understand the motion: Continuity: Av = constant Bernoulli: P + (1/2) pv + pgy = constant. With a 2.0-mm constriction: a. What is the platelet's speed before and after it passes through the constriction? V before 10 11 13 MacBook Pro
