Epithelium of bronchi is

Options

A. Simple cuboidal
B. Pseudostratified columnar
C. Simple squamous
D. Pseudostratified sensory.

Answer

**Step-by-Step Solution:**

1. **Understanding the Bronchi**: The bronchi are part of the respiratory system, branching from the trachea into the lungs. They play a crucial role in conducting air to the lungs.

2. **Identifying the Epithelium Types**: The question asks about the type of epithelium present in the bronchi. The options provided include:
- Simple cuboidal
- Pseudostratified columnar
- Simple squamous
- Pseudostratified sensory

3. **Analyzing Each Option**:
- **Simple Cuboidal Epithelium**: This type is typically found in areas of secretion and absorption, such as the kidney and pancreas. It is not present in the bronchi.
- **Pseudostratified Columnar Epithelium**: This type of epithelium is characterized by its ciliated surface and is commonly found in the respiratory tract, including the bronchi. It helps in trapping and moving mucus and pathogens out of the airways.
- **Simple Squamous Epithelium**: This type is found where diffusion occurs, such as in the alveoli and capillaries. It is not found in the bronchi.
- **Pseudostratified Sensory Epithelium**: This type is found in sensory organs, such as the olfactory region of the nasal cavity. It is not present in the bronchi.

4. **Conclusion**: Based on the analysis, the epithelium of the bronchi is best described as **pseudostratified columnar epithelium**. This type of epithelium contains goblet cells that secrete mucus and cilia that help in clearing pathogens.

5. **Final Answer**: The epithelium of bronchi is **pseudostratified columnar epithelium**.
