Alveolar Sac

[[File:Respiratory_histology_03.jpg|thumb|300px| Alveolar Type I cell - (squamous alveolar) cells form the structure of an alveolar wall.

Alveolar Type II cell - (great alveolar) cells secrete pulmonary surfactant.

  • surfactant is continuously released by exocytosis
  • lowers the surface tension of water and allows the membrane to separate
  • increases the capability to exchange gases.

Macrophages - destroy foreign material and debris.

Compare the cartoon structure with the alveoli histology.
