1
Q
Type I
A
97% of alveolar surfaces:
line the alveoli
Squamous; thin for optimal gas diffusion
2
Q
Type II
A
Pulm surfactant
Reduces tension and prevent atelectasis
Cuboidal and clustered.
Stem cell
3
Q
Clara cells
A
Nonciliated
Columnar with secretory granules.
Secrete components of surfactant;
Degrade toxin, act as reserve cells.
