A 40-year-old man is brought to the emergency department after being exposed to ozone and nitrogen dioxide at a factory. He dies shortly thereafter.

If he had survived, this layer would have likely been regenerated within several weeks by which of the following cells?

A) Clara cells

B) Endothelial cells

C) Reticular cells

My guess is E. type II pneumocytes makes surfactant

[bleedorange]

The answer is correct. E. but it has nothing to do with production of surfactant. In the lungs type II pneumocytes has fibroblastic activity which aids in the reparative process.
