A. a fall in capillary hydrostatic pressure.
B. a fall in interstitial hydrostatic pressure.
C. a fall in arteriolar resistance.
D. either 2 or 3.
E. none of the above.
What do you guys think? I got D.
A fall in arteriolar resistance reduces arteriolar pressure which decreases filtration, isn't it?
So I'll go with B).
Although arterioles can refer to the arterioles that come immediately before the capillary. Reduced resistance, increased flow, increased hydrostatic pressure?
That's why I hate cardiovascular, anything can make logical sense.
I've got that constricting arterioles increases the resistance and downstream blood (capillaries) loose pressure
so vice versa.
