pharynx that is a passage for food and air
laryngopharynx
larynx
voicebox
hollow spaces in bones that produce mucus for the nasal cavities
sinuses
flap of skin that fold over the trachea while swallowing
epiglottis
tube that transports air between the pharynx and bronchi
trachea
two branches of the trachea that lead to the lungs
bronchi
place where bronchi split
carina
air sacs that exchange gases with the pulmonary capillary blood
alveoli
organs that bring oxygen into the body and remove carbon dioxide and waste
lungs
What are the 3 functions of the respiratory system?
bring in oxygen for body cells, expel waste products from blood, produce airflow that makes speech possible
List the organs of the upper respiratory tract.
nose, mouth, pharynx, epiglottis, larynx, trachea
List the organs of the lower respiratory tract.
bronchi, lungs
wall of cartilage that divides the nose into two equal sections
nasal septum
thin hairs located in the nostrils that filters incoming air
cilia
specialized membranes that line the organs of the respiratory organs
mucous membranes
fluid secreted by mucous membranes that protects and lubricates the membranes
mucus
What are the functions of a sinus?
make the skull lighter, help produce sound by resonance, produce mucus

visceral pleura
pleura that covers the inside of the rib cage
parietal pleura
muscle that separates the thoracic cavity from the abdominal cavity, contracts and relaxes to make breathing possible

exchange of oxygen and carbon dioxide
respiration
act of taking in air
inhalation

exhalation
exchange of gas between the body and the environment
external respiration
superficial set of vocal cords that contain mucous membranes for vibration
true vocal cords
deep set of vocal cords that contain muscle fibers
false vocal cords
pointed surface of lung
apex
What kind of tissue are alveoli made of?

exchange of gas between the blood and the cells
internal respiration
part of the brain that regulates breathing
medulla oblongata
What is the respiratory stimulus?
CO2
Where does the exchange of oxygen and carbon dioxide take place?
alveoli
high pitched breathing sound resembling the blowing of wind
stridor
continuous, coarse whistling sound heard during breathing
wheeze
lung sound produced by air passing over retained air secretions
crackle
rattling breathing sound resembling snoring
rhonchi
broad inferior surface of the lung
base
a vibration transmitted through the body
fremitus
