RESPIRATORY SYSTEM Flashcards
(37 cards)
Functions of the respiratory system
- allow gases from the environment to enter the bronchial tree
- allow gas exchange to occur at the respiratory membrane
- permit gases in the lungs to be eliminated through expiration
main external

system and are the first
section of the body’s airway
nose and nasal

tiny hairs in our nose
CILIA

folds or voice reeds
a cartilaginous
tube that connects the larynx to the bronchi of the lungs, allowing the passage of air,
TRACHEA
another term for trachea
WINDPIPE
passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange
BRONCHI

BRONCHIOLES

organs found in the thorax lateral to
the heart and superior to the diaphragm.
LUNGS
what surrounds each lung?
PLEURAL MEMBRANE

is the …..
DIAPHRAGM
a thin sheet of skeletal
muscle that forms the floor of the thorax.
DIAPHRAGM
a chronic disorder involving soreness and swelling of the interior airway walls
ASTHMA
a chronic inflammatory lung disease that
causes obstructed airflow from the lungs
Chronic obstructive pulmonary
disease
Symptoms include breathing difficulty, cough, mucus (sputum)
production and wheezing. It’s
typically caused by long-term exposure to irritating gases or
particulate matter, most often from
cigarette smoke.
