Question
Biology Question on excretory products and their elimination
The net filtration pressure in the glomerulus of the kidney is
A
25 mm Hg
B
10 mm Hg
C
35 mm Hg
D
70 mm Hg
Answer
25 mm Hg
Explanation
Solution
1. GHP (Glomerular Hydrostatic Pressure): Pressure in the glomerulus. It is about 75 mm Hg
2. BCOP (Blood Colloidal Osm otic Pressure) : It is due to the plasma proteins (albumin, globulin and fibrinogen) in the glomeruli
? Plasma proteins are not filtered
? BCOP opposes filtration and is about 32 mm Hg
