The main function of pulmonary surfactants is to reduce the surface tension at the air/liquid interface in the lungs.
Explanation:
This is achieved by forming a surface film that consists of a mono layer which is highly enriched in dipalmitoylphosphatidylcholine and bilayer lipid/protein structure closely attached to it.
Pulmonary surfactant is a mixture of lipids and proteins which is secreted by the epithelial type II cells into the alveolar space.
