Number of erthyrocytes formed per hour is

Options

A. 1 million
B. 90 million
C. 1000 million
D. 100 billion

Answer

To determine the number of erythrocytes (red blood cells) formed per hour, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to find out how many erythrocytes are produced in one hour.

2. **Know the Production Rate**: According to the information provided, it is estimated that in healthy adults, approximately 100 billion erythrocytes are produced each day.

3. **Convert Daily Production to Hourly Production**:
- There are 24 hours in a day.
- To find the hourly production, we divide the daily production by the number of hours in a day:
\[ \text{Hourly Production} = \frac{\text{Daily Production}}{24} \]
- Substituting the values:
\[ \text{Hourly Production} = \frac{100 \text{ billion}}{24} \approx 4.17 \text{ billion} \]

4. **Final Result**: Therefore, the number of erythrocytes formed per hour is approximately 4.17 billion.

### Conclusion:
The number of erythrocytes formed per hour is approximately 4.17 billion.
