Quizplus · Accepted Answer

Respiratory distress syndrome in newborns is caused by a lack of surfactant, which is a substance present in the lungs that helps to reduce surface tension and prevent the collapse of the alveoli during expiration. Without surfactant, the alveoli may collapse and lead to respiratory distress. Low oxygen concentration and high oxygen concentration can also lead to respiratory distress in newborns but are not the primary cause. A lack of a respiratory membrane is not a known cause of respiratory distress syndrome in newborns.
