ID: 96917 • Letter: 1

Question

1) Higher blood osmotic pressure (c) than interstitial fluid osmotic pressure (t), and low capillary permeability to plasma proteins

2) Thick, muscular arteriole walls in lower legs

3) Very tight skin around lower legs

4) Vasoconstricted precapillaries in lower legs

5) Prominent lymphatic system

Match each mechanism (above, 1-5) with its immediate physiological consequence/result (below, a-e).

a) Increases Pt

b) Increases resistance, which decreases blood flow to the feet

c) Increases return of “leaked” fluid from the blood

d) Decreases net filtration rate in capillaries

e) Increases resistance, which decreases blood flow to the feet

Explanation / Answer

1. b- increses resistance , which decreases blood flow to feet

2. e- increases resistance, which decrese blood flow to feet

3. a- increases Pt

4. c- increases return of "leaked" fluid from the blood

5. d- decreases net filtration rate in capillaries
