Gas Exchange Process
1. Inhale O2 into lungs
2. CO2 is a waste product of cellular Respiration
(C6H12O6 + 6O2
6CO2 + 6 H2O + ATP )
3. CO2 is removed from the cell through the cell
membrane and into the capillary.
4. Blood travels throughout the body and the capillaries
are picking up CO2 from the cell and carries it to the
lungs
5. When CO2 in the blood arrives in the lungs it is
exhaled
6. At the same time O2 from the alveoli moves into the
capillary and is transported throughout the body to
the cell
