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) 99 mm Hg
B) 24 mm Hg
C) 69 mm Hg
D) 30 mm Hg
E) 84 mm Hg

Question

Quizplus · Accepted Answer

The net filtration pressure is calculated as the difference between the glomerular capillary pressure and the sum of the capsular space pressure and the colloid osmotic pressure: 69 mm Hg - (15 mm Hg + 30 mm Hg) = 24 mm Hg.
