Options

A. 0.7 million
B. 0.9 million
C. 1.2 million
D. 1.6 million

Answer

To determine the number of nephrons in each kidney of a human, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Kidney**:
- The kidney is made up of various structures, with the nephron being the basic functional and structural unit.

2. **Identify the Components of a Nephron**:
- Each nephron consists of two main parts: the renal corpuscle (which includes the glomerulus and Bowman's capsule) and the renal tubule (which includes the proximal convoluted tubule (PCT), Henle's loop, and distal convoluted tubule (DCT)).

3. **Know the Number of Nephrons in a Kidney**:
- Research and studies indicate that each human kidney contains approximately 1.2 million nephrons.

4. **Evaluate the Options Provided**:
- The question provides multiple-choice options: 0.7 million, 0.9 million, 1.2 million, and 1.6 million.

5. **Select the Correct Answer**:
- Based on the information gathered, the correct answer is 1.2 million nephrons per kidney.

### Final Answer:
The number of nephrons in each kidney of man is approximately **1.2 million**.
