Gas Exchange

?
Ventilation
The exchange of air between the atmosphere and the lungs – achieved by the physical act of breathing
1 of 5
Gas Exchange
The exchange of oxygen and carbon dioxide between the alveoli and bloodstream (via passive diffusion)
2 of 5
Cell Respiration
The release of energy (ATP) from organic molecules – it is enhanced by the presence of oxygen (aerobic)
3 of 5
Alveoli
the site of gas exchange
4 of 5
Pneumocytes
(or alveolar cells) are the cells that line the alveoli and comprise of the majority of the inner surface of the lungs
