Final answer:
The force exerted from the pressure of the blood vessels that pushes filtrate into the renal tubules is the Glomerular Blood Hydrostatic Pressure (GBHP), which is the primary force driving glomerular filtration.
Step-by-step explanation:
Understanding Glomerular Filtration
The force exerted from the pressure of the blood vessels that pushes filtrate out of the capillaries (glomerulus) and into the renal tubules is known as the Glomerular Blood Hydrostatic Pressure (GBHP). This hydrostatic pressure is the pressure produced by the fluid in the glomerular capillaries. It is the primary factor that drives the glomerular filtration process, which involves the movement of water and solutes from the blood into the glomerular capsule.
On the other side is the Capsular Hydrostatic Pressure (CHP) and the Blood Colloid Osmotic Pressure (BCOP). The Net Filtration Pressure (NFP) is the result of these pressures working together and is defined as:
NFP = GBHP - [CHP + BCOP]
In the scenario given, where filtration occurs through a semipermeable membrane in the kidneys, GBHP is the driving force for this process, making it the correct answer to the student's question.
