What is false concerning the movement of fluid between capillaries and interstitial space?

A)The osmotic pressure of the interstitial fluid is less than the blood osmotic pressure.


B) The net filtration pressure is usually zero.


C)Blood osmotic pressure moves fluid from the interstitial space to the capillary.


D)Blood hydrostatic pressure forces fluid from the capillary to the interstitial space.


E) The hydrostatic pressure of the interstitial fluid is largely unimportant in determining fluid


movement.What is false concerning the movement of fluid between capillaries and interstitial space?
B) is false since ( the net filtration pressure is positive)


NFP (net filtration pressure)= capillary pressure-interstitial fluid pressure-plasma colloid osmotic pressure+interstitial fluid colloid osmotic pressure ( it just mean that the tendency of fluids in the capillaries are to leak out towards the interstitial space)
