PhysioEX 8.0 Exercise 5

We can answer answer a few activity questions for you if you would post the questions. Without seeing the questions we do not know if you are using PhysioEx for A&P or PhysioEx for Human Physiology.

It's the physio ex 8.0 A&P but im pretty sure both books are almost identical.
example of the first question in activity 1:
what happened to the fluid flow rate as the radius of the flow tube was increased?

1.What happened to the fluid flow rate as the radius of the flow
tube was increased?  The fluid flow rate will increase.

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? exponential___ __



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

This is what I got.

Activity 1
What happened to fluid flow as the radius of the flow tube was increased? increased
Because fluid flow is proportional to the fourth power of the radius, ____ in tube radius cause ____ in fluid flow. increases; increases
The relationship between fluid flow and flow tube radius is ____ exponential
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 ____ constricted;dilated

Activity 2
How does fluid flow change as viscosity decreases? decreases
Fluid flow versus viscosity is a(n) ____ relationship inverse
The effect of viscosity compared with the effect of radius on fluid flow is ____ neither
Anemia would ____ blood flow decrease
Blood flow would ____ if the number of blood cells were increased increase
Blood viscosity would ____ in conditions of dehydration, resulting in ____ blood flow. increase;decreased

Activity 3
The shorter the flow tube, the ____ he fluid flow. slower

Activity 4
As driving pressure increases, fluid flow ____. increases
How does the plot in this activity differ from the plots for tube radius, viscosity, and tube length? It is exponential
The repeating alternation between systole and diastole is called. heart cycle
The slow depolarization of cardiac nodal or conduction cells toward the threshold level that sets the intrinsic heart rate is called. pacemaker potential
Cardioaccelerator and cardioinhibitor reflex centers are located in which part of the brain? Medulla oblongata
