As the fetus approaches term,there is a decrease in the secretion of intrapulmonary fluid,which assists in reducing the pulmonary resistance to blood flow and facilitates the initiation of air breathing.Lung expansion after birth stimulates the release of surfactant-a slippery,detergent-like lipoprotein.Surfactant causes decreased surface tension within the alveoli,which allows for alveolar re-expansion following each exhalation.Under normal circumstances,by the 34th to 36th week of gestation,surfactant is produced in sufficient amounts to maintain alveolar stability.
