The epithelial tissue present on the inner surface of bronchioles and trachea -

Options

A. Squamous
B. Cuboidal
C. Glandular
D. Ciliated

Answer

**Step-by-Step Solution:**

1. **Identify the Epithelial Tissue Types**: The question asks about the type of epithelial tissue present on the inner surface of bronchioles and trachea. The options provided are squamous, cuboidal, glandular, and ciliated.

2. **Understand the Function of Epithelial Tissue**: Epithelial tissues serve various functions, including protection, absorption, secretion, and movement. In the respiratory tract, the movement of mucus and other substances is crucial for maintaining cleanliness and functionality.

3. **Focus on the Respiratory Tract**: The bronchioles and trachea are parts of the respiratory system. It's important to consider the specific functions of epithelial tissues in this area, particularly regarding the movement of mucus.

4. **Identify the Correct Type of Epithelial Tissue**: The ciliated columnar epithelium is known for having hair-like structures called cilia on its surface. These cilia help to move mucus and trapped particles out of the respiratory tract, which is essential for keeping the airways clear.

5. **Conclusion**: Based on the above reasoning, the epithelial tissue present on the inner surface of bronchioles and trachea is ciliated columnar epithelium.

**Final Answer**: The epithelial tissue present on the inner surface of bronchioles and trachea is ciliated columnar epithelium.
