The epithelium found in hollow organs (like bronchioles ) are originally ……….epithelium bearing fine brush - like structures on its free surface.

Options

A. columnar
B. glandular
C. squamous
D. compound

Answer

To solve the question regarding the type of epithelium found in hollow organs like bronchioles, we need to identify the characteristics of the epithelium that bears fine brush-like structures on its free surface.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the type of epithelium that is found in hollow organs such as bronchioles and has fine brush-like structures on its surface.

2. **Identifying Brush-like Structures**: The fine brush-like structures mentioned in the question are typically microvilli. Microvilli are small projections that increase the surface area of the epithelium, which is important for absorption and secretion.

3. **Considering the Options**:
- **Option 1: Columnar Epithelium**: This type of epithelium is characterized by its column-like shape and is often associated with microvilli, especially in areas where absorption and secretion occur (like in the intestines and bronchioles). This option is likely correct.
- **Option 2: Glandular Epithelium**: This type of epithelium is specialized for secretion and does not typically have microvilli. It is found in glands rather than in hollow organs like bronchioles. This option is incorrect.
- **Option 3: Squamous Epithelium**: This type of epithelium consists of flat cells and is involved in processes such as diffusion and filtration. It does not have microvilli. This option is also incorrect.
- **Option 4: Compound Epithelium**: This type of epithelium consists of multiple layers of cells and is found in areas subject to abrasion. It does not typically have microvilli. This option is incorrect.

4. **Conclusion**: After analyzing the options, the only type of epithelium that fits the description of having brush-like structures (microvilli) and being found in hollow organs like bronchioles is **Columnar Epithelium**.

### Final Answer:
The correct answer is **Columnar Epithelium**.
