Ciliated epithelium occurs in

Options

A. Trachea and lungs
B. Trachea and liver
C. Bronchioles and fallopian tubes
D. Bronchioles and lungs

Answer

### Step-by-Step Solution:

1. **Understanding Ciliated Epithelium**:
- Ciliated epithelium is a type of epithelial tissue that has hair-like structures called cilia on its surface. These cilia help in the movement of particles or fluids across the epithelial surface.

2. **Identifying Locations of Ciliated Epithelium**:
- Ciliated epithelium is commonly found in various parts of the respiratory and reproductive systems.

3. **Analyzing the Options**:
- **Trachea**: The trachea contains ciliated pseudostratified columnar epithelium, which helps in trapping and moving particles out of the airways.
- **Lungs**: The lungs primarily consist of squamous epithelium, which is not ciliated.
- **Bronchioles**: The bronchioles also have ciliated pseudostratified columnar epithelium, aiding in the movement of mucus and particles.
- **Fallopian Tubes**: The fallopian tubes contain ciliated columnar epithelium, which helps in the movement of the egg towards the uterus.

4. **Conclusion**:
- Based on the analysis, the correct answer is that ciliated epithelium occurs in both the bronchioles and the fallopian tubes.

### Final Answer:
Ciliated epithelium occurs in bronchioles and fallopian tubes.
