1. What two parameters are responsible for creating the movement (filtration and reabsorption) of fluid across the capillary wall?
Blood pressure and water pressure (osmotic) are responsible for creating the movement of fluid across the capillary wall.
2. Find a diagram of a capillary – copy/paste and cite the source. http://www.biog1105-1106.org/demos/105/unit7/fluidexchange.html
3. Under normal circumstances, what components of the blood cross the capillary wall?
Under normal circumstances, interstitial fluid, water, and other small solutes can cross the capillary wall, although blood cells cannot.
4. Cytokines, like histamine and leukotrienes, are secreted by damaged cells in Dave’s ankle. How do these cytokines cause inflammation?
These cytokines cause inflammation because they cause vasodilatation which makes blood rush to the injured site.
5. How does the application of ice to the ankle affect blood flow through the capillaries?
The ice causes the capillaries to constrict, which limits the blood flood to the injury, and limits the swelling.
6. How does the removal of ice from the ankle affect blood flow through the capillaries and the cytokines?
When the ice is removed from the ankle, it will cause the capillaries and cytokines go back to normal, which will cause the blood flow to increase once again.
7. How does compression, which is provided by an elastic (Ace) bandage wrapped around the damaged ankle, decrease inflammation?
The Ace bandage will constrict the capillaries, just like the ice, but the Ace bandage does this physically.
8. How does elevation of the damaged ankle decrease inflammation?
Elevation of the damaged ankle will cause the blood to return back to the heart, and the elevation makes it more difficult for the excessive amount of blood to travel up to the ankle.
1. What problems are there in Suzie’s life, and does she exhibit any peculiar signs and symptoms?
Suzie feels that her mother gives her
