Starling Forces

Question 1

Starling equation

Answer 1

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

Question 2

if fluid movement is POSITIVE

Answer 2

FILTRATION (fluid moves out of the capillary)

Question 3

if fluid movement is NEGATIVE

Answer 3

ABSORPTION (fluid moves into the capillary)

Question 4

Favors FILTRATION

Answer 4

Capillary Hydrostatic Pressure

Question 5

Favors ABSORPTION

Answer 5

Interstitial Hydrostatic Pressure

slightly negative d.t. lymphatic pump

Question 6

favors ABSORPTION

Answer 6

Capillary Oncotic Pressure

increased by increases in plasma protein concentration

Question 7

favors FILTRATION

Answer 7

Interstitial Oncotic Pressure

determined by interstitial protein concentration

Question 8

Hydraulic conductance of capillary wall (capillary permeability)

promotes filtration

Answer 8

Filtration coefficient
