Quizplus · Accepted Answer

A key feature of surfactant production,which is the basis for the success of replacement therapy with exogenous compounds,is the recycling activity in surfactant production.Most surfactant (90% to 95%)is taken back into the alveolar type II cell,reprocessed,and resecreted.For this reason,exogenously administered surfactant is successful in replacing missing surfactant with one or two doses.The exogenous surfactant is taken into the type II cells and becomes the surfactant pool,through the reuptake and recycling mechanism.
