Ch. 12 Respiratory System Flashcards
External respiration
exchange of air in lung capillaries
how does external respiration work
- oxygen is inhaled into the air sacs
- immediately passes into capillaries
- carbon dioxide passes from capillaries into air sacs, to be exhaled
Internal respiration
exchange of gases in the cells
how does internal respiration work
- occurs simultaneously between cells and capillaries
- oxygen passes out of the bloodstream into the tissue
- carbon dioxide passes out of tissues back into the bloodstream to travel to lungs
mediastinum
middle of chest where trachea divides into two branches
bronchi
each leads to a separate lung
lungs
lobes are not mirror images
hilum
blood vessels, nerves, lymphatic tissue
adenoids
lympathic tissue in the nasopharynx
alveolus
air sac in the lung
bronchioles
the smallest branches of the bronchi
bronchus
the branch of the trachea that is a passageway into the lung
carbon dioxide
exhaled through the lungs
cilia
thin hairs attached to mucous membrane epithelium lining the respiratory tract
diaphragm
contracts to pull air into the lungs
relaxes to push air out
epiglottis
lid like piece cartilage that covers the larynx
expiration
breathing out
inspiration
breathing in
larynx
voice box
lobe
division of the lung
nares
opening through the nose carrying air into the nasal cavities
paranasal sinus
one of the air cavities in the bones near the nose
parietal pleura
outer fold of pleura lying closer to the ribs and chest wall
pharynx
the throat
pleura
double folded membrane surrounding each lung
pleural cavity
space between the folds of the pleura
respiration
the process of moving air into and out of the lungs
trachea
windpipe
visceral pleura
inner fold of pleura lying closer to the lung tissue

tapping on a surface to determine the underlying structure
pleural rub
pleural layer are inflamed and have lost their lubrication
rale
crackle
rhonchus
continuous snorelike sound in the throat of bronchial tubes
sputum
mucus that is coughed up from the lower airways
stridor
high pitched wheezing sound
upper respiratory disorders
coup
diphtheria
nosebleed
atelectasis
accumulations of fluid, blood or air in pleural cavity
pneumothorax
air gathers in the pleural cavity
magnetic resonance imaging
magnetic waves create images
bronchoscopy
fiberoptic or rigid endoscope inserted into the bronchial tubes for diagnosis, biopsy or collection of secretions
endotracheal intubation
placement of tube from mouth to trachea to establish airway
thracentesis
surgical puncture to remove fluid from pleural space
