A) the plasma concentration of protein is reduced.
B) endothelial permeability goes up.
C) capillary hydrostatic pressure is elevated.
D) all of the above
E) none of the above

Question

Quizplus · Accepted Answer

Edema is caused by an accumulation of fluid in the interstitial space, and this can occur due to several situations: decreased plasma protein concentration (which can reduce colloid osmotic pressure), increased endothelial permeability (which allows fluid to escape more easily), and elevation of capillary hydrostatic pressure (which increases the pressure gradient and forces fluid out of the capillaries). Therefore, all of the choices (A, B, and C) can favor edema.
