pluera
|
thin membrane that lines and covers the lungs
|
|
|
primary bronchi
|
2 large tubes that branch into secondary bronchi which branch into smaller tubes called brockioles with lead to smaller alveolar ducts and into the alveoli which are tiny air sacs that are the site of gas exchange surrounded by cappilaries
|
|
|
IRDS
|
infant respiratory distress syndrome
usually seen in premies (less than 37 weeks under 5 lbs) lack of surfacant which would normally allow air in and out easily |

|
inflamed bronchi
results in cough of sputum (mucous and pus)1 |
