|
|
|
Windpipe |
Trachea |
|
|
|
Actual site of gas exchanges |
Alveoli |
|
|
|
Pleural layer covering the thorax walls |
Parietal pleura |
|
|
|
Pleural layer covering the lungs |
Visceral pleura |
|
|
|
Lumen of larynx |

|
|
|
In healthy lungs, it is always lower than atmospheric pressure |
Intrapleural pressure |
|
|
|
Pressure of air outside the body |
Atmospheric pressure |
|
|
|
As a decreases, air flows into the passageways of the lungs |
Intrapulmonary pressure |
|
|
|
As it increases over atmospheric pressure, air flows out of the lungs |
Intrapulmonary pressure |
|
|
|
If this pressure becomes equal to the atmospheric pressure the lungs collapse |
intrapleural pressure |
|
|
|
Rises well over Abbotsford pressure during a forceful cough |
Intrapulmonary pressure |
|
|
|
Also known as intra-alveolar pressure |
Intrapulmonary pressure |
|
|
|
Period of breathing when it enters the lungs |
Inspiration |
|
|
|
Exchange of gases between the systemic capillary blood and body cells |
Internal respiration |
|
|
|
Ultimate flushing of air into and out of the lungs |
Ventilation |
Breathing |
|
|
Period of breathing when air leaves the lungs |
Expiration |
|
|
|
Sudden inspiration resulting from spasms of the diaphragm |
Hiccup |
|
|
|
A deep breath is taken, the glottis is closed, and the air is forced out of the lungs against the glottis, clears lower respiratory passageways |
Coughing |
|
|
|
As just described, but it clears the upper respiratory passageways |
Sneeze |
|
|
|
Increases ventilation of the lungs, may be initiated by a need to increase oxygen levels in the blood |
Yawn |
|
|
|
Respiratory volume inhaled or exhaled during normal breathing |
Tidal volume |
|
|
|
Air and respiratory passages that does not contribute to gas exchange |

|
|
|
Total amount of exchangeable air |
Vital capacity |
|
|
|
Gas valve that allows gas exchange to go on continuously |
Residual volume |
|
|
|
Amount of air that can still be exhale forcibly after a normal exhalation |
Expiratory Reserve volume |
|
