The exchange of gases between blood and cells is called
pulmonary ventilation
internal respiration
external respiration
cellular respiration
the nose serves all the following functions EXCEPT:
as the initiator of the cough reflex
warming and humidifying the air
cleansing the air
as a passageway for air movement
When the diaphragm and external intercostals muscles contract, which will NOT occur
air moves into the lungs
the intrapleural pressure increases
the diaphragm moves inferiorly
the intrapulmonary pressure decreases
During swallowing, the glottis is covered by
false vocal cord
true vocal cord
epiglottis
Adam's apple
Which of the following describes a correct order of structures in the respiratory passageway
pharynx, trachea, larynx, bronchi, bronchioles
larynx, pharynx, trachea, bronchioles, bronchi
trachea, pharynx, larynx, bronchi, bronchioles
pharynx, larynx, trachea, bronchi, bronchioles
the volume of air that can be exhaled and exhaled during a normal respiration cycle is the
tidal volume
residual volume
inspiratory reserve volume
expiratory reserve volume
During internal and external respiration gases move by
osmosis
active transport
diffusion
endocytosis
The main passageway that leads to the lungs from the throat is the
pharynx
epiglottis
esophagus
trachea
the first branches off the trachea are called
bronchioles
bronchi
arterioles
alveoli
what helps keep the alveoli inflated at the perfect size
surfactant
cilia
mucus
hemoglobin
The dome shaped muscle below the chest cavity is called the
intercostals
rib muscle
diaphragm
coleus
Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called
arterioles
venules
capillaries
bronchioles
the diaphragm is located along the bottom of the
stomach
liver
abdominal cavity
rib cage
cilia that line the walls of air passageways
move the inspired air to the alveoli
moisten the expired air
move the expired air to the nasal cavity
clean the inspired air
The actual exchange of gases occurs at the site of the
larynx
nasal passage
trachea
alveoli
each alveolus
contains many air sacs
is surrounded by capillaries
attaches to the larynx
is a large air sac
when the diaphragm and rib cage muscles relax
the chest cavity enlarges
expiration occurs
inspiration occurs
it is impossible to breath
inspiration occurs when
blood pressure increases
the diaphragm pushes upward
thoracic pressure increases
thoracic volume increases
chamber where passages from the nose and mouth come together
larynx
pharynx
trachea
bronchi
where are the vocal cords located
pharynx
epiglottis
larynx
trachea
The _ are sacs of the lungs where oxygen and carbon dioxide are exchanged by diffusion between air and blood
epiglottis
alveoli
bronchioles
larynx
Sound is produced by vibrations of the
epiglottis
bronchi
glottis
trachea
During inhalation
the rib muscles relax
the diaphragm moves upward
air pressure decreases in the chest cavity
the rib cage moves downward
Breathing is an involuntary action under control of the
cerebrum
pons
medulla oblongata
cerebellum
What prevents the trachea from collapsing
circular bones
bronchi
c-rings of cartilage
alveoli
Internal respiration is at the level of the
organism
cell
lungs
pharynx
Immediately before entering the alveoli, inspired air passes through
veins
trachea
bronchioles
bronchi
