Question

Effective net filtration pressure in the glomerulus in kidney of man is about

• A. + 75 mm Hg
• B. + 80 mm Hg
• C. + 20 to 25 mm Hg
• D. + 50 mm Hg

Answer 1

Answer: (C)

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
