Respiratory System-A
| Question | Answer |
|---|---|
| Resting Tidal Volume | The amount of air moved into or out of lungs during a single respiratory cycle |
| Expiratory Reserve Volume | The amount of air you can voluntarily expell after you have completed a normal respiratory cycle |
| Residual Volume | The amount of air that remains in your lungs even after maximum exhalation |
| Minimal Volume | The amount of air which would remain in your lungs even if they were collapsed |
| Inspiratory Reserve Volume | The amount of air you can take into your lungs over and above tidal volume |
| Inspiritory Capacity | Tidal volume plus IRV |
| Functional Residual Capacity | The amount of air remaining in lungs after a quiet respiratory cycle |
| Vital Capacity | Maximum amount of air that you can move into or out of your lungs in a single respiratory cycle |
| Total lung capacity | Total volume of your lungs (Vital capacity plus residual volume) |
| Anoxia | A condition of tissue oxygen starvation (not limitation) |
| Hypoxia | Low tissue oxygen levels |
| Asthma | An acute respiratory disorder characterized by unusually sensitive, irritated conducting airways |
| Atelectasis | A collapsed lung |
| Bronchitis | Inflamation of bronchial lining |
| cystic fibrosis | A lethal inherited disease caused by an abnormal membrane channel protein; mucous secretions become to thick to be transported easily, leading to respiratory problems |
| Decompresion sickness-alternate name? | The Bends |
| Decompression sickness-definition? | A condition caused by a rapid drop in atmospheric pressure and the resulting formation of nitrogen gas bubbles in body fluids, tissues and organs |
| Emphysema | A chronic, progressice condition characterized by shortness of breath and an inability to tolerate physical exertion |
| Epistaxis | Nosebleed |
| Heimlich maneuver-Alternate name? | Abdominal thrust |
| Heimlich maneuver-definition? | Compression applied to the abdomen just inferior to the diaphram, to force air out of the lungs to clear a blocked trachea or larynx |
| Hypercapnia | Increase in the PC02 of arterial blood |
| Hypocapnea | abnormally low PCO2 |
| Lung cancer-alternate name? | pleuropulmonary neoplasm |
| pleuropulmonary neoplasm | Lung cancer |
| Mountain sickness | An acute disorder resulting from CNS effects due to the low gas partial pressures that occur at high altitudes |
| Pleurisy | An inflamation of the pleaurae, accomplanied by the secretion of excess amounts of pleural fluid |
| pneumonia | A respiratory disorder characterized by fluid leakage into the alveoli or swelling and constriction of the respiratory bronchioles |
| pneumothorax | the entry of air into the pleural cavity |
| The pleural cavity | the space between the viseral and parietal plerae |
| Respiratory Distress Syndrome | A condition resulting from the production of inadequate surfactant and associated alveolar collapse |
| SIDS | Death of an infant to to respiratory arrest. Unkown cause |
| tracheostomy | insertion of a tube directly into the trachea to bypass a blocked or damaged larynx |
| tuberculosis-bacteria? | Myobacterium tuberculosis |
| Composition of air-Nitrogen%? | 78.6% |
| Composition of air-O2%? | 20.9 |
| Composition of air-other than Nitrogen and oxygen? | 0.5%-water, CO2, others |
| Normal Atmospheric Pressure | 760 mm Hg |
| mm Hg | Millimeters of Mercury |
| Partial pressure | The pressure contributed by a single gas in a mixture of gasses |
| Normal partial pressure of O2 in atmosphere | 159 mm Hg |
| Quiet Breathing AKA? | Eupnia |
| Forced Breathing AKA? | Hyperpnea |
| Diaphragmatic breathing | Breathing using the diaphram |
| Costal Breathing | Breathing using the ribs |
