| rales | crackles, fluid in the base of the lungs |
| wheezing | high pitched sound, narrowing or obstruction of airways, seen in asthma |
| stridor | high pitched crowing sound, indicates airway obstruction |
| ventilation | movement of air from external environment to the gas exchange units of the lungs |
| respiratory excursion | also known as dyspnea |
| cyanosis | bluish tinged skin due to lack of O2 |
| apnea | temporary cessation of breathing |
| crepitus | bubble wrap feeling felt under the skin |
| cheyne stokes resp | resp that become faster and deeper, then slower and shallower with a period of apnea |
| thoracentesis | surgical puncture and drainage of the thoracic cavity |
| external respirations | allows O2 and CO2 exchange between lungs and environment |
| internal respirations | the exchange of O2 and CO2 at a cellular level |
| organs of upper resp system | nares, nasal cavity, sinuses, pharynx, larynx, trachea |
| larynx | voice box |
| epiglottis | covers the larynx during swallowing |
| trachea | windpipe |
