6) Edema is caused by all of the following except:
a) an ↑ in capillary permeability
b) a ↓ in plasma proteins
c) a ↓ in ISF colloid osmotic pressure
d) an ↑ in capillary pressure
e) nephrotic syndrome




6) Answer: c
An ↑ in ISF Colloid Osmotic P. leads to edema; ex. of this is Lymphatic blockage.
An ↑ in Capillary Permeability (x.e. acute injury, infections or burns)
An ↑ in Capillary P. (x.e, CHF)
A ↓ plasma proteins (e.g. nephritic syndrome or liver failure)
All of them produce EDEMA.
