Abstract:
Lung surfactant from bronchoalveolar lavage and post-lavaged lung tissue of calf and adult cows was isolated. In both species of the surfactant, the main fractions are: phospholipids and free fatty acids. Phosphatidylcholine was the main phospholipid fraction. Phosphatidylglycerol level is about 4% of total phospholipids. In both phosphatidylcholine and phosphatidylglycerol fractions, palmitic, oleic and linoleic acids are the main fatty acids. There are no differences between bronchoalveolar lavage and post-lavaged lung tissue surfactants and between calf and adult cow surfactants in the aspect of their lipid composition.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
