I need answers to PhysioEx 9.0 Exercise 5 PLEASE

I need answers to Physio 9.0, exercise 5 please.  Just not getting this stuff

Yo. i sent you a PM for this. Check it out and get back to me.

1) Explain how the body establishes a pressure gradient for fluid flow?

2) Explain the effect that the flow tube radius change had on flow rate?

Of course! This is the same thing I expressed in the PM. Thanks.

Discuss the effect that polycythemia would have on the viscosity and on blood flow

How_Mendel[/b}, do not sweat it my friend. We are cool.

Activity 2
1) Describe the components in the blood that affect viscosity?

The hematocrit typically accounts for the viscous component. Other components include the buffy coat and plasma which decrease viscosity.

2)Explain the effect that the viscosity change had on the flow rate?

As viscosity increases, the substance 's ability to flow becomes hindered. Flow decreases with viscosity.

3) Describe the graph of flow versus viscosity?

I would expect the graph to be sigmoidal.

4) Discuss the effect that polycythemia would have on the viscosity and on blood flow?

Polycythemia means increased levels of RBCs, and thus a higher hematocrit content and a higher viscosity.
