PHYSIOEX 8.0 ANATOMY AND PHYSIOLOGY EXERCISE 5

i kindly need help with this .physioex 8.0 for A&P EXERCISE 5


PAGE 65 EXXERCISE 5
1.What happened to the fluid flow rate as the radius of the flow
tube was increased?
Cardiovascular Dynamics 65
FIGURE 5.1 Opening screen of the Vessel Resistance experiment.

PAGE 66 Exercise 5
Circle the correct term within the parentheses: Because
fluid flow is proportional to the fourth power of the radius,
(increases / decreases) in tube radius cause (increases / decreases)
in fluid flow.
2.Is the relationship between the fluid flow rate and the flow
tube radius linear or exponential? _____________________

In this experiment, a simulated motor changes the diameter
of the flow tube.
3.Explain how our blood vessels alter blood
flow.

4.After a heavy meal when we are relatively inactive, we might
expect blood vessels in the skeletal muscles to be somewhat
_________________, whereas blood vessels in the digestive
organs are probably _________________. ?
