Measurement of the Functions of a Nephron Reveals a Glomerular

question 16

Multiple Choice

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 blood 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
