Exchange of gases in the lungs 6.8

what is the advantage of the alveoli being one cell thick
To allow gas to diffuse across easily
1 of 5
What is the advantage of the red blood cells being slowed as they pass through the pulmonary capillaries
It allows for more diffusion time
2 of 5
Why do the alveoli and capillaries have a very large surface area
To allow more gas exchange
3 of 5
Why is there a steep concentration gradient within the lungs
to allow gas exchange to be constantly exchanged
4 of 5
What is the advantage having many alveoli packed together
It means more gas exchange can happen
