Respiration Vocab
| Definition | Term |
|---|---|
| throat | pharynx |
| voice box | larynx |
| "The Guardian of the Airway", it protects the superior opening of the larynx | epiglottis |
| windpipe | trachea |
| right and left, are formed by the division of the trachea | main bronchi |
| the smallest of the conducting passageways | bronchioles |
| small air sacs at the end of the bronchioles | alveoli |
| 3 lobes | right lung |
| 2 lobes | left lung |
| bone supported palate that separates the nasal and oral cavities | hard palate |
| unsupported palate that separates the nasal and oral cavities | soft palate |
| superior portion of the pharynx where air enters from the nose | nasopharynx |
| the middle portion of the pharynx where air and food moves downward | oropharynx |
| inferior portion of the pharynx where air and food moves downward | laryngopharynx |
| the adenoids that are located high in the nasopharynx | pharyngeal tonsil |
| tonsils in the oropharynx at the end of the soft palate | palatine tonsils |
| tonsils that lie at the base of the tongue | lingual tonsils |
| the largest of the hyaline cartilages that protect the larynx, commonly called the "Adam's Apple" | thyroid cartilage |
| inward folds on the lungs that divide lobes | fissure |
| fluid that covers the surface of each lung | visceral pleura |
| lines the walls of the thoracic cavity with a fluid | parietal pleura |
| 4 events of respiration | 1. pulmonary ventilation 2. external respiration 3. respiratory gas exchange 4. internal respiration |
| pulmonary ventilation | air must move into and out of the lungs so that gases in the air sacs (alveoli) of the lungs are continuously refreshed. The process of pulmonary ventilation is commonly called breathing |
| external respiration | gas exchange (oxygen leading and carbon dioxide unloading) between the pulmonary blood and alveoli must take place. Remember that in external respiration, gas exchanges are being made between the blood and the body exterior |
| respiratory gas exchange | oxygen and carbon dioxide must be transported to and from the lungs and tissue cells of the body via the bloodstream |
| internal respiration | at systemic capillaries, gas exchanges must be made between the blood and tissue cell. In internal respirations, gas exchanges are occurring between the blood and cells inside the body |
