Question

If blood pressure is too high, this elevated _________________ can damage the delicate filtration barriers of the glomerulus.

colloid osmotic pressure (π)

fluid pressure (P_fluid)

hydrostatic pressure (P_H)

Answer 1

Option C-Hydrostatic pressure.(PH)

Net filtration pressure = Glomerular blood hydrostatic pressure – [Bowmans capsular hydrostatic pressure + colloid osmotic pressure of blood.

When there is An increase in Arterial or venous pressure -----there will be increased capillary hydrostatic pressure --which favours filtration.

Similarly---A reduction of Arterial or venous pressures---- will reduce capillary hydrostatic pressure --which reduce filtration.

Colloid Osmotic pressure is the pressure induced by proteins,(mainly albumin) in a blood vessel's plasma ,This is Usually independent of Arterial pressure.This pressure changes when there is Hypoproteinemia,Hyperproteinemia,Protein Leakage etc.
