You correctly answered: They are inversely proportional to each other. 1 What e ff ect do you think aplastic anemia (reduced red blood cells) would have on blood ﬂ ow? You correctly answered: increased blood ﬂ ow due to decreased viscosity. 2

Review Sheet Results The variable that you altered in this activity was You correctly answered: viscosity. 1 Increasing viscosity resulted in You correctly answered: decreased ﬂ ow rate. 2 What e ff ect would a decreased hematocrit have on blood ﬂ ow? You correctly answered: decreased viscosity, increased ﬂ ow. 3 What do you predict would be the overall a ff ect on viscosity during dehydration? Your answer: decreased viscosity, increased ﬂ ow . Correct answer: increased viscosity, decreased ﬂ ow. 4 Describe the components in the blood that a ff ect viscosity. You did not answer this question. 1 Explain the e ff ect that the viscosity change had on ﬂ ow rate. How well did the results compare with your prediction? You did not answer this question. 2 Describe the graph of ﬂ ow versus viscosity. You did not answer this question. 3 Discuss the e ff ect that polycythemia would have on viscosity and on blood ﬂ ow.
