Capillary fluid exchange

Question 1

Pnet

Answer 1

[(Pc-Pi)-(pi c - pi i)]

P= pressure
pi = oncotic pressure

Question 2

Edema causes

Answer 2

1) high capillary pressure (HF)
2) low plasma protein (nephrotic, liver failure)
3) high capillary permeability (toxin, infection, burns)
4) high colloid osmotic pressure

Question 3

Net fluid flow

Answer 3

Kf*Pnet

Kf= filtration constant (capillary permeability)
