CH 12 Flashcards
Adenoids
lymphatic tissue in the nasopharynx pharyngeal tonsils
alveolus
air sac in the lung
apex of the lung
tip or uppermost portion of the lung
base of the lung
lower portion of the lung
bronchioles
smallest branches of the bronchi
bronchus
branch of the trachea that is a passage way into the lung bronchial tube
carbon dioxide
gas produced by body cells when oxygen and carbon atoms from food combine; exhaled through the lungs
cilia
thin hairs attached to the mucous membrane epithelium lining the respiratory tract
diaphragm
muscle separating the chest abdomen
epiglottis
lid like piece of cartilage that covers the larynx, preventing food from entering the larynx and trachea during swallowing
glottis
slit like opening to the larynx
hilum (of lung)
midline region where the bronchi blood vessels and nerves enter and exit the lungs
larynx
voice box
lobe
division of a lung
mediastinum
region between the lungs in the chest cavity
oxygen
gas that makes up 21% of the air that we breathe
palatine tonsil
one of a pair of almond-shaped masses of lymphatic tissue in the oropharynx
paranasal sinus
one of the air cavities in the bones near the nose
parietal pleura
outer layer of pleura lying closer to the ribs and chest wall
pharynx
throat
pleura
double layered membrane surrounding each lung
pleural cavity
space between the layers of the pleura
pulmonary parenchyma
essential parts of the lung, responsible for respiration
trachea
windpipe
visceral pleura
inner layer of pleura lying closer to the lung tissue
auscultation
listening to sounds within the body
percussion
taping on a surface to determine the difference in the density of the underlying structure
pleural rub
scratchy sound produced by pleural surfaces rubbing against each other
rales (crackles)
fine crackling sounds heard on auscultation when there is fluid in the alveoli
sputum
material expelled from the bronchi lungs or upper respiratory tract by spitting
stridor
strained high pitched sound heard on inspiration caused by obstruction in the pharynx or larynx
wheezes
continuous high pitched whistling sounds produced during breathing
asthma
chronic inflammatory disorder with airway obstruction due to bronchial and bronchiolar edema and constriction
atelectasis
collapsed lung; incomplete expansion of alveoli
bronchiectasis
chronic dilation of a bronchus, usually secondary to infection
chronic bronchitis
inflammation of bronchi persisting over a long time; type of chronic obstructive pulmonary disease
croup
acute viral infection of infants and children with obstruction of the larynx, accompanied by barking cough and stridor
cystic fibrosis
inherited disorder of exocrine glands resulting in thick mucinous secretions in the respiratory tract that do not drain normally
diptheria
acute infection of the throat and upper respiratory tract caused by the diphtheria bacterium
emphysema
hyperinflation of air sacs with destruction of alveolar walls
epistaxis
nosebleed
