<prompt> Factor which increases the GFR are all except:Increase in glomerular hydrostatic pressureIncrease in tubular hydrostatic pressureEfferent arteriolar constrictionDecrease in plasma oncotic pressure  <response>: Factors affecting the glomerular filtration rate:Changes in renal blood flow.Changes in glomerular capillary hydrostatic pressure.Changes in systemic blood pressure.Afferent or efferent arteriolar constriction.Changes in hydrostatic pressure in Bowmans capsule.Ureteral obstruction. Edema of kidney inside tight renal capsule.Changes in concentration of plasma: dehydration, hypoprotinemia, etc minor factors.Changes in KChanges in glomerular capillary permeability.Changes in effective filtration surface area.Key ConceptDecrease in tubular hydrostatic pressure increases the GFR.Reference: Ganongs Review of Medical Physiology T W E N T Y - F I F T H E D I T I O N page no 679
