Which of the following pairs of parts are formed by the same type of epithelium?

Options

A. Trachea - Bronchiole
B. Pharynx- stomach
C. Pleura -Alveoli
D. Alveoli-intestinal villi

Answer

To solve the question regarding which pairs of parts are formed by the same type of epithelium, we will analyze each option provided:

1. **Trachea and Bronchioles**:
- The trachea is lined with **ciliated pseudostratified columnar epithelium**.
- The bronchioles are lined with **ciliated simple cuboidal epithelium**.
- **Conclusion**: These two do not have the same type of epithelium.

2. **Pharynx and Stomach**:
- The pharynx is lined with **stratified squamous epithelium**.
- The stomach is lined with **simple columnar epithelium**.
- **Conclusion**: These two do not have the same type of epithelium.

3. **Pleura and Alveoli**:
- The pleura (pleural cavity) is lined with **simple squamous epithelium**.
- The alveoli are also lined with **simple squamous epithelium**.
- **Conclusion**: These two have the same type of epithelium.

4. **Alveoli and Intestinal Villi**:
- The alveoli are lined with **simple squamous epithelium**.
- The intestinal villi are lined with **simple columnar epithelium** (specifically enterocytes).
- **Conclusion**: These two do not have the same type of epithelium.

After analyzing all the options, we find that the correct pair formed by the same type of epithelium is:

**Answer: Pleura and Alveoli (both lined with simple squamous epithelium)**.
