Glomerular osmotic pressure and capsular osmotic pressure are equally important in determining the GFR.

Question

Quizplus · Accepted Answer

Glomerular osmotic pressure (created by proteins in the blood plasma) plays a significant role in determining GFR, by opposing the hydrostatic forces. Capsular pressure, on the other hand, is the pressure exerted on the glomerular capillaries by the fluid in Bowman's capsule, which tends to push fluid out of the capillaries and into the nephron. However, it is not equally important in determining GFR compared to glomerular osmotic pressure. The most important factor in determining GFR is the balance between the hydrostatic and osmotic forces acting on the glomerular capillaries.
