Alveolar Sac
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 above diagram structure with the alveoli histology and electron microscope image.
