Respiratory Flashcards
alveolus (alveoli)
Air sac in lung
Bronchioles
Smallest branches of bronchi. Terminal lead to aveolar ducts
Bronchus (bronchi)
Branch of trachea (windpipe) passageway into lung; bronchial tube
Diaphragm
Muscle separates chest and abdomen
Epiglottis
Lid-like cartilage covers larynx when swallowing
Expiration
Breathing out
Glottis
Slit-like opening to larynx
Hilum of the lung
Midline region where bronchi, blood vessels, and nerves enter/exit lungs
Inspiration
Breathing in
Larynx
Voice box

Paranasal sinus
One of air cavities in bones near nose
Parietal pleura
Outer layer of pleura by ribs/chest wall
Pharynx
Throat; includes nasopharynx,oropharynx,laryngopharynx
Pleura
Double-layered membrane around lung
Pleural cavity
Space between folds of pleura
Pulmonary parenchyma
Part of lung responsible for respiration; bronchioles & alveoli
Respiration
Breathing
Trachea
Windpipe
Visceral pleura
Inner layer of pleura by lung tissue
Adenoids
Lymphatic tissue in nasopharynx; pharyngeal tonsils
Auscultation
Listening to sounds w/in body
Percussion
Tapping on surface to determine diff in density of underlying structure
Pleural rub
Scratchy sound from pleural surfaces rubbing
Rales (crackles)
Crackling sounds from fluid in alveoli
Rhonchi (rhonchus)
Rumbling from bronchi obstructed by sputum
Sputum
Material expelled from bronchi, lungs, or upper resp. tract by spitting
Stridor
Obstruction in pharynx or larynx causing high pitched sound
Croup
Viral infection in kids w/ larynx obstruction, cough & stridor
Diphtheria
