A decrease in capillary blood pressure and an increase in blood protein both increase interstitial fluid volume.

Question

Quizplus · Accepted Answer

A decrease in capillary blood pressure would actually decrease interstitial fluid volume by reducing the force that pushes fluid out of capillaries into the interstitial space. An increase in blood protein (specifically plasma proteins) would increase the osmotic pressure within capillaries, drawing fluid back into them from the interstitial space, thus decreasing interstitial fluid volume.
