| Process of ambient air moving into the lungs and exchanging gases |
|
|
Term
|
Definition
Exchange of O2 and CO2 between cells and environment
Cells require O2 and must get rid of CO2
Cells have no contact with atmosphere
Cells must rely on external respiration of pulmonary function |

Term
| Functions of the conduction and respiratory zones |
|
Definition
Extensive capillarization in alveoli walls
Very thin blood-gas barrier
-Alveoli membrane and capillary membrane |

|
Term
| Know the mechanics of ventilation |
|
Definition
Air flow
-Movement of air into and out of lungs
-Occurs because of the intrapulmonary pressure changes
-Intrapulmonary pressure changes are the result of changes in the size of the thoracic cavity
"Negative Pressure Ventilation" => Intrapulmonic Pressure |
