What is the similarity between bronchi and fallopian tube ?

Options

A. Pseudostratified epithelium
B. Ciliated epithelium
C. Cuboidal epithelium
D. Columnar epithelium

Answer

### Step-by-Step Solution

1. **Identify the Structures**:
- Understand what bronchi and fallopian tubes are.
- **Bronchi**: These are the major air passages of the respiratory system that branch from the trachea into the lungs.
- **Fallopian Tubes**: These are part of the female reproductive system, serving as the pathway for the ovum (egg) to travel from the ovaries to the uterus.

2. **Determine Their Functions**:
- **Bronchi**: Their primary function is to conduct air to and from the lungs, facilitating gas exchange.
- **Fallopian Tubes**: Their main function is to transport the ovum from the ovaries to the uterus, and they are also the site where fertilization typically occurs.

3. **Examine the Tissue Types**:
- Both bronchi and fallopian tubes are lined with specific types of epithelial tissues.
- **Ciliated Epithelium**: This type of tissue is characterized by hair-like structures called cilia that help in the movement of substances. In bronchi, cilia help move mucus and trapped particles out of the airways, while in fallopian tubes, cilia assist in moving the ovum towards the uterus.

4. **Identify the Similarity**:
- The key similarity between bronchi and fallopian tubes is that both structures are lined with **ciliated epithelium**. This tissue type is crucial for their respective functions in moving air and the ovum.

5. **Select the Correct Answer**:
- Based on the analysis, the correct answer to the question "What is the similarity between bronchi and fallopian tube?" is that both are lined with **ciliated epithelium**.
