Differentiate between type I and type II cells of the lungs.

The type I cells secrete surfactant and the type II cells will give rise to bronchiolar smooth muscle cells.

The type I cells form alveolar walls and the type II cells secrete surfactant.

Both type I and type Il cells produce surfactant.

The type I cells produce cartilage for larger airways and the type II cells give rise to the ciliated cells lining the trachea.
