Composicio in composifion that composition and function of the natural lung surfactant differ among vertebrates depending on the pulmonary anatomy and respiratory physiology and that its quality varies with the pulmonra of the animals, in the present work a biochemical and biophysical characterization of a pig lung surfactant from young and adult animals was studied in order to evaluate the quality of these surfactants.
