In human lungs are divided into lobes

Options

A. 3 right & 2 left lobes
B. 2 right & 3 left lobes
C. 2 right & 2 left lobes
D. 3 right & 3 left lobes

Answer

**Step-by-Step Solution:**

1. **Understanding Lung Structure**: The human lungs are divided into lobes. The right lung is larger and is divided into three lobes, while the left lung is smaller and has two lobes.

2. **Identifying the Lobes of the Right Lung**:
- The right lung consists of:
- Superior lobe (uppermost)
- Middle lobe (middle section)
- Inferior lobe (bottom section)
- The right lung lobes are separated by:
- The horizontal fissure (between the superior and middle lobes)
- The oblique fissure (between the middle and inferior lobes)

3. **Identifying the Lobes of the Left Lung**:
- The left lung consists of:
- Superior lobe (uppermost)
- Inferior lobe (bottom section)
- The left lung lobes are separated by:
- The oblique fissure (between the superior and inferior lobes)

4. **Counting the Lobes**:
- Right lung: 3 lobes (Superior, Middle, Inferior)
- Left lung: 2 lobes (Superior, Inferior)

5. **Conclusion**: Therefore, in total, the human lungs have 3 lobes on the right side and 2 lobes on the left side.

6. **Selecting the Correct Option**: Based on the above information, the correct answer is that the right lung has 3 lobes and the left lung has 2 lobes.

**Final Answer**: The correct option is the first one: 3 lobes on the right and 2 lobes on the left.
