Chapter 8_Respiratory System Flashcards
respiration
combined activity of various processes that supply oxygen to all body cels and remove CO2
Pulmonary ventilation
breathing
inspiration
breathing air into lungs (inhalation)
expiration
expiring air our of lungs (exhalation)
pulmonologist
physician who specializes in the anatomy, physiology, and pathology of the lungs
Structures of respiratory tract
nasal cavity, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli
Structures of upper respiratory tract
nose, nasal cavity, paranasal sinuses, pharynx, larynx
Structures of lower respiratory tract
trachea, bronchi, bronchioles, alveoli, lungs
palate
separates nasal and oral cavity
epiglottis
covers larynx during swallowing (not part of rest tract)
diaphram
muscular wall separating the abdomen from the thoracic cavity - controls and relaxes inspirations and expirations
phren/o
diaphragm (also mind - schizophrenic)
lobes of lung
right (3), left (2)
pleura
membrane surrounding lung and check cavity (pleural cavity - space between)
paranasal sinuses
air-filled paired cavities in various bones around nose (frontal, ethmoid, maxillary, sphenoid)
alveol/o
alveolus (alveoli)
bronch/o, bronchi/o
bronchus (bronchi)
epiglott/o
epiglottis
laryng/o
larynx (voice box)
lob/o
lobe
nas/o, rhin/o
nose
phrenic
pertaining to the diaphragm (also pertaining to the mind - schizophrenic)
pleur/o
pleura
pharyng/o
pharynx (throat)
pneum/o, pneumon/o, pulm/o, pulmon/o
lung
trache/o
trachea (windpipe)
oximetry
photo diagnostic method of monitoring blood oxygen saturation in arteries (non-invasive - finger or ear)
instrument = oximeter
oxygen saturation
percent og hemoglobin molecules that are saturated with oxygen
-pnea
breathing (apnea, dyspnea, etc.)
eupnea
normal respiration (15-20 breathes per minute)
dyspnea
labored or difficult breathing (complains of SOB)
apnea
temporary absence of breathing (sleep apnea)
orthopnea
condition where breathing is uncomfortable in any position except sitting erect or standing
bradypnea
abnormally slow breathing (less then 12 breathes per minute)
tachypnea
fast breathing (more than 20 breathes per minute) - caused by exercise or disease
hyperpnea
increased respiratory rate or breathing that is deeper than normal
hyperventilation
increased aeration in the lungs; reduced CO2 in body and disrupts homeostasis (hyperpnea can lead to this)
atel/o
imperfect
coni/o
a relationship to dust
embol/o
embolus (detached traveling intravascular mass)
home/o
sameness
-ole
little
ox/o
oxygen
silic/o
Silica
spir/o
to breath (sometimes spiral)
spirometry
measurement of the amount of air taken into and expelled by the lungs
vital capacity (VC)
largest volume of air that can be exhaled after maximum inspiration
acute respiratory failure
inability of the lungs to perform their ventilatory function
hypoxia
deficiency in O2 (can result from reduces O2 in air at elevation or from anemia)
anoxia
deficiency in O2
nares
nostrils
nasal septum
separates the nasal cavities
sinusitis
inflammation of the sinus
pharyngitis
inflammation of the pharynx
laryngopharynx
lower part of pharynx where it divides into larynx and esophagus
laryngitis
inflammation of the larynx
aphonia
absence of voice
aphasia
inability to communicate through speech, writing or signs (improper brain functioning)
dysphonia
weak voice
dysphasia
speech impairment resulting from bran lesion
laryngalgia
pain of the larynx
glottis
vocal apparatus of the larynx; consists of vocal cords (or folds) and area between them
sputum
mucus secreted by mucous membranes
dyspnea
difficult breathing
orthopneic
difficult breathing except for when sitting erect (note: “a” in pnea is dropped)
pneumothorax
air or gas in check cavity (typically caused by injury)
hemothorax
blood in pleural cavity (often with pneumothorax)
pulmonary embolus
obstruction of pulmonary artery or one of its branches
embolism
sudden blocking of an artery by a foreign material brought by the circulating blood
thrombus
when an embolus is a blood clot
polyp
growth protruding from mucous membrane
pharyngeal / laryngeal
pertaining to the pharynx and larynx
adult respiratory distress syndrome (ARDS)
disorder characterized by respiratory insufficiency and hypoxemia
asthma
paroxysmal (occurs in sudden attacks / reoccurance) dyspnea accompanied by wheezing
atelectasis
incomplete expansion of the lung or portion of it
bronchiectasis
chronic dilation of a bronchus with secondary infection usually involving the lower part of the lung
bronchography
radiology of the bronchi following injection of radiopaque substance (bronchogram produced)
chronic obstructive pulmonary disease (COPD)
disease that decreases the lung’s ability to perform their ventilatory function
emphysema
chronic pulmonary disease characterized by an increase in the size of alveoli and destructive changes in their walls (breathing difficult)
influenza
acute, contagious respiratory infection (chills, headache, fever, aches)
nasal polyp
abnormal protruding growth from nasal mucosa
pleuritis
inflammation of the pleura (aka pleurisy)
pneumoconiosis
respiratory condition caused by inhalation of dust particles
severe acute respiratory syndrome (SARS)
infectious respiratory disease spread by close contact and caused by a coronavirus
silicosis
form of pneumoconiosis resulting from inhalation of dust containing silica
sudden infant death syndrome (SIDS)
sudden, expected death of an apparently normal and healthy infant
tuberculosis (TB)
infections disease caused by bacterium, called mycobacterium tuberculosis; often chronic and usually effects lungs; small round nodules, called tubercles, are produced in lung
aphyxiation
suffocation
heimlich maneuver
method of dislodging food or obstruction from windpipe
ventilator
machine used for prolonged mechanical ventilation of the lungs
endotracheal intubation
insertion of an airway tube through the mouth (orotracheal) or nose (nasotrachea) into the trachea
decongestants
eliminate of reduce swelling or congestion
antitussives
prevent of relieve coughing
antihistamine
treats colds and allergies
