Question

The net pressure gradient that causes the fluid to filter out of the glomeruli into the capsule is

• A. 50 mmHg
• B. 75 mmHg
• C. 20 mmHg
• D. 30 mmHg

Answer 1

Answer: (C)

A) The net pressure gradient that causes the fluid to filter out of the glomeruli into the capsule is 20 mm Hg.

B) 75 mm Hg is too high for the fluid to filter out of the glomeruli into the Bowman's capsule.

C) About 20% of the plasma fluid is filtered out into the Bowman's capsule due to a net filtration rate of 10-15 mm Hg. So the net pressure gradient that causes the fluid to filter out is 20 mm Hg.

D) The net pressure gradient is 20 mm Hg.

So, the correct answer is '20 mmHg'
