1

Abnormalities of growth and development of the lung are origins of whatt?

'Adult' Lung disease

2

What are the 5 stages of lung morphogenesis?

Embryonic
Pseudo-glandular
Canalicular
Saccular
Alveolar

3

During embryonic development, what is not possible?

Gas exchange is not possible

4

In which stage would you start to see myofibroblasts?

Pseudo-glandular

5

During which stage does life become possible?

The Canalicular stage

6

When does surfactant generally become apparent?

When life first becomes possible

7

When does the diaphragm develop?

The pseudo-glandular stage

8

During the first few breaths of the child, the lungs do what?

Change from a fluid secreting organ to a fluid absorbing one

9

The failure of the function of the lung following birth in a child can lead to what?

Wet Lung

10

What does surfactant do?

Stabilisies alveoli and promotes gas exchange

11

What is neonatal lung disease?

When there is no proper ventilation due to surfactant deficiency

How can neonatal lung disease be prevented?

With antenatal steroids
