Respiration Vocab

DefinitionTerm
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
