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)
