Lab Report Cardiovascular Dynamics Studying the Eﬀect of Blood Viscosity on Blood Flow Rate Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 Which of the following is not a formed element? You correctly answered: plasma protein. 2 Thrombocytopenia is a reduction in platelets. What eﬀect do you think this could have on blood viscosity? You correctly answered: decrease blood viscosity. 3 Which of the following does not contribute to the viscosity of the blood? You correctly answered: oxygen level in the blood. 4 Viscosity most directly aﬀects You correctly answered: peripheral resistance. Experiment Results Predict Question 1 Predict Question: What eﬀect do you think increasing the viscosity will have on the ﬂuid ﬂow rate? Your answer: The ﬂuid ﬂow rate will decrease. Stop & Think Questions 1 What is the relationship between ﬂuid ﬂow and viscosity? You correctly answered: They are inversely proportional to each other. 2 What eﬀect do you think aplastic anemia (reduced red blood cells) would have on blood ﬂow? You correctly answered: increased blood ﬂow due to decreased viscosity. Experiment Data Flow (ml/min) Radius (mm) Viscosity Length (mm) Pressure (mm Hg) 490.6 5.0 1.0 50 100 245.3 5.0 2.0 50 100 163.5 5.0 3.0 50 100 122.7 5.0 4.0 50 100 98.1 5.0 5.0 50 100 81.8 5.0 6.0 50 100 70.1 5.0 7.0 50 100 61.3 5.0 8.0 50 100 Post-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 The variable that you altered in this activity was You correctly answered: viscosity. 2 Increasing viscosity resulted in You correctly answered: decreased ﬂow rate. 3 What eﬀect would a decreased hematocrit have on blood ﬂow? You correctly answered: decreased viscosity, increased ﬂow. 4 What do you predict would be the overall aﬀect on viscosity during dehydration? You correctly answered: increased viscosity, decreased ﬂow. Review Sheet Results 1 Describe the components in the blood that aﬀect viscosity. Your answer: Plasma proteins, white blood cells, red blood cells, and platelets aﬀect viscosity in the blood. 2 Explain the eﬀect that the viscosity change had on ﬂow rate. How well did the results compare with your prediction? Your answer: As predicted, increasing the viscosity, or thickness of the ﬂuid will decrease the ﬂow rate due to the density increase. 3 Describe the graph of ﬂow versus viscosity. Your answer: The graph of ﬂow versus viscosity are inverse proportional. 4 Discuss the eﬀect that polycythemia would have on viscosity and on blood ﬂow. Your answer: The eﬀect of polycythemia would proceed in an increase in viscosity and a decrease in blood ﬂow.
