1
Q
Describe the pressure gradients that are required for air to enter the lung
A
Alveolar pressure must be less than barometric pressure
2
Q
What is the flow rate of air proportional to

The difference between alevolar and atmospheric (barometric) pressure
3
Q
Other than pressure differences what else is flow rate proportional to?
A
Any factor that increases airway resistance
4
Q
Flow rate formula
A
V. = (PB-PA)/ R
