Glomerular filtration rate or GFR is the rate of the volume of filtrate formed by all renal corpuscles of both kidneys per unit time that is 120 ml/ min. The GFR depends on the pressure gradient in the glomerulus mainly its hydrostatic pressure.
The GFR is directly proportional to the glomerular blood pressure as the blood pressure increases, the hydrostatic pressure also increases which increases the GFR as more water and solutes enter the bowman's capsule. With the decrease in the blood vessels, the GFR decreases.
