Starling Forces

Question 1

Pc

Answer 1

capillary pressure

pushes fluid out of capillary

Jv = net fluid flow = Kf [(Pc − Pi) − ς(πc − πi)]
Kf = permeability of capillary to fluid
ς = permeability of capillary to proteins

Question 2

Pi

Answer 2

interstitial fluid pressure

pushes fluid into capillary

Question 3

πc

Answer 3

plasma colloid osmotic (oncotic) pressure

pulls fluid into capillary (plasma proteins)

Question 4

πi

Answer 4

interstitial fluid colloid osmotic pressure

pulls fluid out of capillary (proteoglycans)
