respiratory Flashcards
upper respiratory
nasal cavities, sinus cavities, pharynx, larynx
coarse hairs in nose, first defense
vestibular region
roof of nose, smell and taste
olfactory
humidifies and warms air before going into system
respiratory region
paranasal sinuses
air filled cavities behind skull around nose; frontal, ethmoid, maxillary, and sphenoid
throat
pharynx
section of pharynx air passes through, location of pharyngeal tonsils and eustachian tubes
nasopharynx
pharynx region behind oral cavity, air food and liquid pass through, contains palatine and lingual tonsils
oropharynx
pharynx region where air food and liquids pass, food and liquid continue to esophagus and air to trachea
laryngopharynx
lower respiratory tract
trachea, bronchi, bronchioles, alveoli, lungs
where does air go from larynx
trachea
after trachea, what passageways guide air to 5 lobes?
bronchi
where does gas exchange occur at ends of bronchioles?
alveoli, which are covered in capillaries
what muscle allows breathing
diaphragm
area of brain that controls breathing process
medulla oblongata
temporary breathing interuption
apnea
slow breathing
bradypnea
periods of apnea and gradually increasing respirations
cheyne-stokes respiration
difficult/painful breathing
dyspnea
normal breathing
eupnea
deeper-than-normal breathing
hyperpnea
faster than normal and deeper breathing
hyperventilation
breathing too slow and shallow
hypoventilation
easier breathing when sitting up straight
orthopnea
crackling breathing; fluid or mucus in airway
rales
rattling or high-pitched snoring when breathing; narrowing of airways (asthma or resp. infection)
rhonchi
harsh, high pitched during breathing, airway obstruction
stridor
fast breathing
tachypnea
drawing in foreign body during inspiration
aspiration
periodic attacks of dyspnea, spasm of bronchial tubes of swelling of bronchi mucus membrane
asthma
