**Question 25**

The type II alveolar cells are important because they ___.

- o produce surfactant
- o form a layer of thin epithelial cells
- o are made of basement membrane
- o secrete mucus

**Explanation:**
This question tests the understanding of the function of type II alveolar cells in the lungs. Students should identify that the primary function of type II alveolar cells is to produce surfactant, a substance that reduces surface tension in the alveoli and prevents the collapse of lung alveoli during exhalation. This is crucial for efficient gas exchange and overall lung function.
