During what timeframe does a fetus have enough mature structures to breathe on its own if born prematurely? Describe the other structures that develop during this phase.
In terms of lung development, why does a premature fetus have difficulty with independent breathing?
What is surfactant? What cells produce it and how does it work i.e. how specifically does it affect surface tension and alveolar structure (remember La Place's law). Lastly, in the course of term fetal development, explain what mechanism comes into play to assure the sufficient production of surfactant before a term delivery.
What is "hyaline membrane disease"? Name 2 medications that may be used to treat this condition - one before delivery, one after. Lastly, briefly explain the theory behind treatment with CPAP (continuous positive airway pressure) - how may this be dangerous?

This is a good question Your baby's lungs don't need air at this time, the fetal lungs don't function as lungs until birtharrow_forward
