|
Term
|
Definition
| air movement in and out of lungs so that the gases in the alveoli are contiuously changed and refreshed. aka: ventilation, breathing |
|
|
Term
|
Definition
| the gas exchange between the blood and the air-filed chambers of the lungs (oxygen loading/carbon dioxide unloading) |
|
|
Term
| Transport of respiratory gases |
|
Definition
| the transport of respiratory gases b/t the lkungs and tissue cells of the body accomplished by the cardiovasular system, using blood as the transport vehicle. |

|
Definition
| lobelike structures which increase the air turbulence, |
|
|
Term
|
Definition
| surround the nasal cavity, in the frontal sphenoid, ethmoid, and maxillary bones. Act as resonance chambers in speech and the mucosae warm and moisten the incoming air. |

Definition
| separate the nasal passages from the oral cavity |
|
|
Term
|
Definition
| failure of the palatine bones and/or the palatine processes of the maxillary bones to fuse medially, causes difficulty in breathing and oral cavity functions such as sucking, mastication, and speech. |

Term
|
Definition
| lies posterior to the nasal cavity and is continuous with it via the posterior nasal aperture, aka the internal nares. an air passage |

|
Term
|
Definition
| an indented area where the bronchi plunge into the lungs |
|
|
Term
| C-shaped cartilaginous rings |
|
Definition
| allow the esophagus to expand while reinforcing the trachea walls to maintain an open passageway. |
|
|
Term
|
Definition
| produced by air rushing through the large respiratory passageways |
|
|
Term
| vesicular breathing sounds |
|
Definition
| sounds of air filling the alveolar sacs and resembles the sound of a rustling or muffled breeze. |
|
|
Term
|
Definition
| amount of air inhaled or exhaled with each breath under resting conditions (500mL) |
|
|
Term
| Inspiratory reserve volume (IRV) |
|
Definition
| Amount of air that can be forcefully inhaled after a normal tidal volume inhalation (3100 mL) |
|
|
Term
| Expiratory reserve volume (ERV) |
|
Definition
| Amount of air that can be forcefully exhaled after a normal tidal volume inhalation (1200) |
|
|
Term
|
Definition
| Maximum amount of air that can be exhaled after a maximal inspiration (4800mL) VC = TV + IRV + ERV |

Term
|
Definition
| forced vital capacity: measures the amount of gas expelled when the subject takes the deepest possible breath and then exhales forcefully and rapidly. |
|
|
Term
|
Definition
| forced expiratory volume: percentage of the vital capacity that is exhaled during specific time intervals of the FVC test. FEV1 is the amount exhaled during the first second. 75-85% can be exhaled in first second. |
