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.
Glomerular Filtration Rate (GFR) quantifies the volume of filtrate the kidneys produce each minute.
It serves as a critical indicator of kidney function, reflecting the blood filtration efficiency.
Step 2: Measurement of GFR.
GFR is affected by factors including blood pressure, glomerular surface area, and glomerular membrane permeability.
Typical GFR values are between 90 and 120 mL/min.
Step 3: Analyzing other options.
- (A) Osmotic Pressure: This refers to solute pressure in the blood, not filtrate volume.
- (C) Net Filtration Pressure: NFP drives filtration across the glomerular membrane but is not the filtrate volume produced.
- (D) Capsular Hydrostatic Pressure: CHP is the pressure within Bowman's capsule, influencing filtration rate but not the volume itself.
Step 4: Conclusion.
Consequently, the correct response is (B) Glomerular Filtration Rate (GFR).
