PhysioEx 10 Exercise 5 Activity 2

What is the relationship between fluid flow and viscosity?

They are inversely proportional to each other.

Thrombocytopenia is a reduction in platelets. What effect do you think this could have on blood viscosity?

decrease blood viscosity.

Increasing viscosity resulted in

decreased flow rate.

What effect would a decreased hematocrit have on blood flow?

decreased viscosity, increased flow.

What effect do you think aplastic anemia (reduced red blood cells) would have on blood flow?

increased blood flow due to decreased viscosity.

What did you predict would be the overall affect on viscosity during dehydration?

increased viscosity, decreased flow.

Which of the following does not contribute to the viscosity of the blood?

oxygen level in the blood.

Viscosity most directly affects

peripheral resistance.

Which of the following is not a formed element?

plasma protein.

The variable that you altered in this activity was

viscosity.
