, At this point inhalation has occurred.
Air rich in oxygen is now in the alveoli.
The air now has to enter the blood capillaries and
then be transported to the cells.
Therefore we shall now look at the gas exchange
at lung level and then the movement of oxygen
to the cells.
, Thediagram below shows us the events that occur
during gas exchange at the lungs
Gaseous Exchange at the alveoli
