Starling Forces Flashcards
1
Q
Starling equation
A
Jv = Kf (Pc-Pi) - (πc-πi)
Jv = fluid movement Kf = hydraulic conductance Pc = capillary hydrostatic pressure Pi = interstitial hydrostatic pressure πc = capillary oncotic pressure πi = capillary interstitial pressure
2
Q
if fluid movement is POSITIVE
A
FILTRATION (fluid moves out of the capillary)
3
Q
if fluid movement is NEGATIVE
A
ABSORPTION (fluid moves into the capillary)
4
Q
Favors FILTRATION
A
Capillary Hydrostatic Pressure
5
Q
Favors ABSORPTION
A
Interstitial Hydrostatic Pressure
slightly negative d.t. lymphatic pump
6
Q
favors ABSORPTION
A
Capillary Oncotic Pressure
increased by increases in plasma protein concentration
7
Q
favors FILTRATION
A
Interstitial Oncotic Pressure
determined by interstitial protein concentration
8
Q
Hydraulic conductance of capillary wall (capillary permeability)
promotes filtration
A
Filtration coefficient
