3. What is DVT? What are some causes of this? What could be a possible
complication of DVT?
4. What are the three factors that change resistance in blood flow? Provide

atherosclerosis have on vessel radius?
5. Review the concept of diffusion. Be sure to know what travels through
endothelial wall versus the intercellular clefts. Also, explain what
transcytosis is.
6. What is hydrostatic pressure? What is the difference between blood HP and
interstitial fluid HP?
7. What is colloid osmotic pressure? What is the difference between blood COP
and interstitial fluid COP?
8. The following pressures are measured in a pt….
Blood HP = 33 mmHg
Blood COP = 24 mmHg
IF COP = 4 mmHg
What is the net filtration pressure at the arterial end?
If the blood HP at the venous end is 14 mmHg… What is the net filtration
pressure at the venous end?
9. What is the role of the lymphatic system?
10. Define edema. What are the three causes of edema? Be sure to explain
Kwashiokor in detail.
