Clinicаl Applicаtiоn: Surfаctant reduces the surface tensiоn оf the alveoli, preventing them from collapsing. Under normal conditions, surfactant is produced and removed at a constant rate, resulting in a thin, continuous layer of surfactant lining the interior wall of the alveoli. Either too much or too little surfactant results in a homeostatic imbalance. The respiratory disease pulmonary alveolar proteinosis (PAP) results from an excessive accumulation of surfactant within the alveoli. Although the presence of a thin layer of surfactant is necessary for proper lung function, excess surfactant increases the overall thickness of the respiratory membrane, which is the liquid-gas boundary where the respiratory gases cross. Another breathing disorder is respiratory distress syndrome, which occurs in approximately half of the premature babies born prior to 26 weeks. This disorder is due to the lack of sufficient surfactant being produced in Type-II pneumocytes within the lungs. Insufficient surfactant production can also occur due to genetic abnormalities related to surfactant metabolism. Increased production of surfactant would __________________
