Question

The amount of filtrate formed in all renal corpuscles of both kidneys each minute is:

• A. Osmotic Pressure
• B. Glomerular Filtration Rate (GFR)
• C. Net Filtration Pressure (NFP)
• D. Capsular Hydrostatic Pressure (CHP)
• E.

Hint:

Remember: GFR reflects kidney function and is a critical parameter in assessing renal health.

Answer 1

The Correct Option is B

Step 1: Understanding GFR.
The Glomerular Filtration Rate (GFR) is the volume of filtrate produced by the kidneys per minute.
It is an important marker of kidney function, indicating how well the kidneys are filtering blood.
Step 2: Measurement of GFR.
GFR is influenced by factors such as blood pressure, the surface area of the glomeruli, and the permeability of the glomerular membrane.
Normal GFR values range from 90 to 120 mL/min.
Step 3: Analyzing other options.
- (A) Osmotic Pressure: Osmotic pressure refers to the pressure exerted by solutes in the blood, not the amount of filtrate.
- (C) Net Filtration Pressure: NFP is the pressure that drives filtration across the glomerular membrane, but it’s not the amount of filtrate produced.
- (D) Capsular Hydrostatic Pressure: CHP refers to the pressure exerted by the filtrate within the Bowman's capsule, affecting filtration rate but not the volume.
Step 4: Conclusion.
Therefore, the correct answer is (B) Glomerular Filtration Rate (GFR).
