Write true or false
The lining of blood vessels, lung alveoli and kidney tubules are all made up of epithelial tissue.

Answer

To determine whether the statement "The lining of blood vessels, lung alveoli and kidney tubules are all made up of epithelial tissue" is true or false, we can analyze each component mentioned in the statement.

### Step-by-Step Solution:

1. **Identify the Lining of Blood Vessels:**
- The lining of blood vessels is known as the endothelium, which is a type of epithelial tissue.
- **Conclusion:** True for blood vessels.

2. **Identify the Lining of Lung Alveoli:**
- The lung alveoli are lined with simple squamous epithelium, which allows for efficient gas exchange.
- **Conclusion:** True for lung alveoli.

3. **Identify the Lining of Kidney Tubules:**
- The kidney tubules are lined with cuboidal epithelium, which is also a type of epithelial tissue.
- **Conclusion:** True for kidney tubules.

4. **Final Assessment:**
- Since all three structures (blood vessels, lung alveoli, and kidney tubules) are indeed lined with epithelial tissue, the statement is true.

### Final Answer:
**True**
