Cardiovascular Dynamics Review Questions and Answers Graded A+
Explain ho the body establishes a pressure gradient for fluid flow. - Answers Establishing a difference in
pressure at both ends.
Explain the effect that the flow tube radius change had on flow rate. How well did the results compare
with your prediction? - Answers Increased radius = increased blood flow
Describe the effect that the radius changes have on the laminar flow of a fluid? - Answers In the fully
constricted vessel, more blood is in contact within the vessel wall and there is less laminar flow.
Why do you think the plot was not linear? - Answers Exponential relationship between 2 variables.
Describe the components in the blood that affect viscosity. - Answers Presence of plasma proteins and
formed elements (WBC, RBC, platelets)
Explain the effect that the viscosity change had on flow rate. How well did the results compare with your
prediction? - Answers Increased viscosity decreased blood flow because it makes blood thicker
Describe the graph of flow versus viscosity - Answers It was not linear. Exponential showed relationship
as inversely proportional
Discuss the effect that polycythemia would have on the viscosity and on blood flow - Answers Increasing
number of RBV would increase viscosity and decrease blood flow
Which is more likely to occur, a change in blood vessel radius or a change in blood vessel length. Explain
why? - Answers Blood vessel radius because length stays constant when we reach adulthood.
Explain the effect that the change in blood vessel length had on flow rate. - Answers Increased blood
vessel length decreased flow rate.
Explain why you think blood vessel radius can have a larger effect on the body than changes in blood
vessel length? - Answers Radius is multiplied to the 4th power, length is not
Describe the effect that obesity would have on blood flow and why? - Answers Obesity would decrease
blood flow because blood vessel lengthens increase when we gain weight.
Explain the effect that pressure changes had on flow rate. How well did the results compare with your
prediction? - Answers Increase in pressure increased blood flow
Explain why pressure changes are not the best way to control blood flow? - Answers Diameter changes
are easier for the body to make. Pressure changes require the heart to be able to respond to force.
