Select the part of the animal body with its correct tissue type.

Options

A. Columnar Epithelium - Blood vessel
B. Cuboidal Epithelium - Stomach lining
C. Squamous Epithelium - Lung air sac
D. Ciliated Epithelium - Food pipe

Answer

To solve the question of selecting the part of the animal body with its correct tissue type, we will analyze each option provided and determine whether the tissue type corresponds correctly with the specified body part.

### Step-by-Step Solution:

1. **Analyze the First Option: Columnar Epithelium - Blood Vessels**
- Columnar epithelium is not the correct type of tissue that lines blood vessels. Instead, blood vessels are lined by **simple squamous epithelium**. Therefore, this option is incorrect.

2. **Analyze the Second Option: Cuboidal Epithelium - Stomach Lining**
- The stomach lining is primarily composed of **simple columnar epithelium**, not cuboidal epithelium. Hence, this option is also incorrect.

3. **Analyze the Third Option: Squamous Epithelium - Lung Air Sac**
- The lung air sacs, known as alveoli, are indeed lined with **simple squamous epithelium**. This tissue type is suitable for gas exchange due to its permeability. Therefore, this option is correct.

4. **Analyze the Fourth Option: Ciliated Epithelium - Food Pipe (Esophagus)**
- The esophagus is lined with **stratified squamous epithelium** in adults, not ciliated epithelium. Ciliated epithelium is more commonly found in the respiratory tract. Thus, this option is incorrect.

### Conclusion:
The correct match is **Option 3: Squamous Epithelium - Lung Air Sac**.
