Answer

To answer the question regarding the presence of the oblique fissure in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Lungs**:
- The lungs are the primary respiratory organs in humans, located in the thoracic cavity. They are responsible for gas exchange.

2. **Identifying the Fissures in the Lungs**:
- The lungs have several internal structures, including lobes, bronchi, bronchioles, and alveoli. The oblique fissure is one of the important internal structures.

3. **Locating the Oblique Fissure**:
- The oblique fissure is a septum that divides the lungs into lobes. It is present in both the right and left lungs.

4. **Understanding the Lobes of the Lungs**:
- The right lung is divided into three lobes: upper lobe, middle lobe, and lower lobe. The oblique fissure separates the upper and lower lobes.
- The left lung has two lobes: upper lobe and lower lobe, separated by the oblique fissure.

5. **Conclusion**:
- Since the oblique fissure is present in both the right and left lungs, the answer to the question is that the oblique fissure is present in both lungs.

### Final Answer:
The oblique fissure is present in both the right lung and the left lung.
