Submit Answers to the Following Questions:

Part I:

What two parameters are responsible for creating the movement (filtration and reabsorption) of fluid across the capillary wall?

Ÿ The hydrostatic pressure (or blood pressure) and osmotic pressure (water pressure) are responsible for balancing and creating the movement of fluid across the capillary wall

Find a diagram of a capillary – copy/paste and cite the source.

Under normal circumstances, what components of the blood cross the capillary wall?

Ÿ Interstitial fluid travels across capillary walls. Water and other small solutes can also diffuse across the wall but blood cells can’t

Cytokines, like histamine and leukotrienes, are secreted by damaged cells in Dave’s ankle. How do these cytokines cause inflammation?

Ÿ Cytokines from injured calls induce the expression of E-selection on endothelial cells, which functions similarly to P-selection

How does the application of ice to the ankle affect blood flow through the capillaries?

Ÿ The application of ice causes constriction of the capillaries. This disease the blood flow to the ankle and reduces swelling

How does the removal of ice from the ankle affect blood flow through the capillaries and the cytokines?

Ÿ This will return the blood flow and cytokines to normal. The blood flow increase

How does compression, which is provided by an elastic (Ace) bandage wrapped around the damaged ankle, decrease inflammation?

Ÿ The ace bandage will physically...
