how many renal corpuscles are approximately present in each kidney of human

Options

A. one million
B. two million
C. three million
D. four million

Answer

To determine how many renal corpuscles are approximately present in each kidney of a human, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Renal Corpuscles**:
- Renal corpuscles are the structural and functional units of the kidney involved in the filtration of blood. They consist of the glomerulus and Bowman's capsule.

2. **Identifying the Number of Nephrons**:
- Each kidney contains nephrons, which are the functional units of the kidney. Each nephron has one renal corpuscle.

3. **Estimating the Number of Nephrons**:
- It is estimated that each human kidney contains approximately 1 million nephrons.

4. **Conclusion**:
- Since each nephron has one renal corpuscle, this means that there are approximately 1 million renal corpuscles in each kidney.

5. **Final Answer**:
- Therefore, the approximate number of renal corpuscles in each human kidney is 1,000,000 (1 million).
