If the hydrostatic pressure of blood flowing through the glomerular capillaries and forcing fluid through the leaky endothelium was 60mmHg, the pressure caused by the lack of proteins in the fluid inside Bowman's capsule was 32 mmHg, and the pressure caused by the inability of the capsule to expand in volume was 18mm Hg, what would the net filtration pressure (in mmHg) be?

The net filtration pressure is 10 mmHg.

Explanation:

for calculating net filtration we will plus the pressure inside boman's capsule with pressure caused by inability of capsule expansion and then subtract them from total pressure in leaky epithelium.

net filtration pressure = total blood pressure in leaky epithelium - total blood pressure in capsule

as we know that total blood pressure in capsule is 32 + 18 = 50 mmHg

therefore

net filtration pressure = 60 - 50

net filtration pressure = 10 mmHg
