Sunset last night, Hamilton Island
This is the LO number that the work of breathing post from yesterday was given by mistake, so surfactant fell through the gaps…
I am sure you would find the answers to these in either West or Nunn’s (Lumb) books. I used Nunn because I am still on holidays.
BT_PO 1.10 Surfactant properties and role in respiratory mechanics
Surface tension in the alveoli is reduced by the presence of surfactant T/F
Surfactant ensures that surface tension is equal throughout the lung T/F
Surfactant release is stimulated by high volume lung inflation T/F
Surfactant plays a role in keeping the alveoli free from transudate T/F
Surfactant has an important immunological function in the lung T/F
Why is surfactant important in preventing collapse of small alveoli? Which physical law determines pressure within a sphere? If you do a little mathematical equation looking an pressure within an alveolus with a 0.1mm sphere and one with a 0.2mm sphere assuming equal surface tension, you will be able to work out the answer to the second statement.
Again my best wishes for those of you with vivas today
