A

Alveolar Sacs

25
2 types of Alveoli Epithelium
Pneumocyte type I and Pneumocyte type II
26
Lining of Pneumocyte I (Alveolocytes)
Simple Squamous Alveolar Epithelium
27
What is Pneumocyte II
Surfactant Secreting Cells
28
This decreases tension in alveoli that prevents it from collapsing
Surfactants
