Glomerular Filtration Rate is increased when: (A) Plasma oncotic pressure is increased, (B) Glomerular hydrostatic pressure is decreased, (C) Tubular hydrostatic pressure is decreased, (D) Increased renal blood flow
Answer is D. Ans. (d) Increased renal blood flow(Ref: Ganong, 25th ed/p.677)GFR decreases whenever there is increase in colloid osmotic pressure of the glomerulusGFR decreases whenever there is decrease in Glomerular capillary hydrostatic pressureGFR decreases whenever there is increase in tubular hydrostatic pressureGFR increases whenever there is increase in renal blood flow
