The type of ephithelial cells which line the inner surface of fallopian tubes smaller bronchi and bronchioles

Options

A. Cubical epithelium
B. Ciliated epithelium
C. Squamous epithelium
D. Columnar epithelium

Answer

To answer the question regarding the type of epithelial cells that line the inner surface of fallopian tubes, smaller bronchi, and bronchioles, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of the Structures**:
- The fallopian tubes are responsible for transporting the ovum from the ovaries to the uterus.
- The smaller bronchi and bronchioles are involved in the respiratory system, facilitating the exchange of gases (oxygen and carbon dioxide).

2. **Consider the Type of Movement Required**:
- Both the fallopian tubes and the bronchioles require a mechanism to move substances (the ovum and air, respectively).
- This movement is typically aided by specialized structures on the epithelial cells.

3. **Recognize the Role of Cilia**:
- Cilia are hair-like structures that extend from the surface of certain epithelial cells.
- They beat in a coordinated manner to move materials along the surface of the epithelium.

4. **Determine the Type of Epithelium**:
- Given that cilia are involved in the movement of materials in both the fallopian tubes and bronchioles, the type of epithelium that contains cilia is known as **ciliated epithelium**.

5. **Select the Correct Answer**:
- Based on the above reasoning, the correct answer to the question is **B. ciliated epithelium**.

### Final Answer:
The type of epithelial cells which line the inner surface of fallopian tubes, smaller bronchi, and bronchioles is **B. ciliated epithelium**.
