Measurement of the functions of a nephron reveals a glomerular capillary pressure of 69 mm Hg,and a pressure in the capsular space of 15 mm Hg.Assuming that the colloid osmotic pressure is 30 mm Hg,and that essentially no plasma proteins are filtered by the glomerulus,what is the net filtration pressure in this case?
A)30 mm Hg
B)24 mm Hg
C)69 mm Hg
D)84 mm Hg
E)99 mm Hg

Net filtration pressure (NFP) is the difference between glomerular capillary pressure (GCP) and the pressure in the capsular space, subtracted by the colloid osmotic pressure (COP). 
NFP = (GCP - capsular pressure) - COP 
NFP = (69 mm Hg - 15 mm Hg) - 30 mm Hg 
NFP = 24 mm Hg
