Answer: c. glomerular filtration pressure.
Step-by-step explanation:
Glomerular filtration is the process of renal filteration in this the blood fluid is filtered across the capillaries of the glomerulus.
The pressure by which the fluid in the blood is filtered across the capillaries in the glomerulus. It is a renal process and also called as the renal ultrafilteration. It is the force of hydrostatic pressure inside the glumerulus. The force of pressure affected by the pressure of the blood on the blood vessels is the driving force that pushes out the filterate out of the capillaries into the slits of the nephron.
