16. Describe the purpose of surfactant. Covers the luminal surface and keeps the alveoli
from sticking together during exhalation.
17. List and describe the two types of alve- Type 1, Type II. Type I form the very thin simple
olar epithelium. squamous epithelium of the alveoli in junction with
capillaries.Type II produce and secrete pulmonary
surfactant which is needed throughout the alveolar
surface to keep the alveoli open. In addition, Type
II cells can divide to replace damaged Type I cells.
