What is the role of surfactant in respiration? - respiratory air flow
In this the kind of laboratory of physiology .. Helping Hand!
1. What was the effect of reducing the radius of the air tube on the respiratory volumes?
2. What is the role of surfactant in breathing?
3. What happens if surfactant were not present?
4. What happens when a pneumothorax?
5. Why is it important to maintain intra-thoracic pressure less than atmospheric pressure?
Thank you!

1) decreased
2) the surface tension of the liquid in the cells, allowing them to more easily
3) very difficult to breathe ... By neonatal survival long after the stage of development that make surfactant (~ 24 weeks)
4) The pleural cavity contains the lungs and a hole is no longer the "negative" holding the pressure in the lungs in relation to the volume of the chest wall ... Lung side hole is shrinking.
5) so that outside air can enter the lungs.
