The normal glomerular filtration rate in humans is

Options

A. 125ml/min by each kidney
B. 125ml/min by both the kidneys taken together
C. 125 ml/ hour by each kidney
D. 125 ml/ hour by both the kidneys taken together

Answer

To determine the normal glomerular filtration rate (GFR) in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Glomerular Filtration**:
- Glomerular filtration is the process by which blood is filtered in the kidneys. This process occurs in the glomeruli, which are tiny structures in the kidneys.

2. **Identify the Normal GFR**:
- The normal GFR for a healthy adult human is approximately 125 ml per minute. This value represents the total filtration rate from both kidneys combined.

3. **Clarify the Measurement**:
- It is important to note that the 125 ml per minute figure is not the filtration rate for each kidney individually, but rather the combined filtration rate of both kidneys.

4. **Consider the Options**:
- When presented with multiple-choice options, ensure to select the one that states the GFR as 125 ml per minute for both kidneys together, as this is the accurate representation of the normal GFR.

5. **Conclusion**:
- Therefore, the correct answer to the question regarding the normal glomerular filtration rate in humans is 125 ml per minute.

### Final Answer:
The normal glomerular filtration rate in humans is **125 ml per minute** (for both kidneys combined).
