Question

What will be the EFP, if BCOP is $-30$, CHP is $-20$ and GHP is $+70$?

• A. $+30$ mm Hg
• B. $+120$ mm Hg
• C. $+20$ mm Hg
• D. $60$ mm Hg

Answer 1

The correct option is B $+120$ mm Hg

The effective filtration pressure depends upon three parameters- GHP (Glomerular Hydrostatic Pressure), BCOP (Blood Colloid Osmotic Pressure), and CHP (Capsular Hydrostatic Pressure).

We have, EFP = GHP – (BCOP + CHP)

If BCOP is −30, CHP is −20 and GHP is +70, then

EFP = 70 – (-30 – 20) = +120 mm Hg.

So, the correct answer is '+120 mm Hg'.
