Explain the
function of
the
respiratory
system.
To carry out gas
exchange
between the
external and
internal
environment

Identify the
structure
described.
1. Contain a ciliated
mucus membrane
A
B
Nasal cavity and trachea
D
2. Voice box larynx
3. Aids in breathing
diaphragm

4. Throat
pharynx
5. Windpipe trachea
H
Which is the correct sequence for the path of
oxygen through the respiratory system?
Nasal cavity
Pharynx
Larynx
Trachea
Bronchi
Bronchioles
Alveoli
1. The tubes that branch from the
trachea are the bronchi
2. The dome shaped muscle below the
chest cavity is called the diaphragm
3. During swallowing, the air passage of
the pharynx is covered by the epiglottis
4. Alveoli in the lungs are connected to the
bronchi by a network of tiny tubes
called bronchioles
5. Breathing is controlled by the chemistry
of your blood as it interacts with the
carbon dioxide
The diagram shows a
rbc in part of a
capillary. Area X is:
1.a nephron in a kidney
2.an alveolus in a lung
3.a villus in the small
intestine
4.a cell in the liver
Explain what happens to gases during
gas exchange in the alveoli.
Oxygen in alveoli diffues into
capillaries (blood).
Carbon dioxide in capillaries (blood)
diffuses into alveoli.
1. Where are the vocal cords located in the body?
larynx
2. Breathing is an involuntary process controlled
by the which part of the brain?
medulla
3.What prevents the trachea from collapsing?
rings of cartilage
4. Where does the actual exchange of gases
occur? alveoli
5. During gas exchange where does the oxygen
and carbon dioxide go?
O2 diffuses into capillaries. CO2 diffuses out
of capillaries and into alveoli.
trachea
The ______
is a long straight
tube that carries air from
the back of the throat to
the lungs.
What structures trap foreign
particles and bacteria in the
nose and trachea?
a) pharynx
b) epiglottis
c) cilia
d) trachea
The order of air movement with in
the lungs is best described as
a) bronchioles to bronchi to
alveoli
b) bronchi to bronchioles to alveoli
c) trachea to bronchi to alveoli
d) bronchi to alveoli to bronchioles
Where are the vocal cords
located in the body?
Larynx
During swallowing, the air passage of
the pharynx is covered by the
epiglottis
The FIRST branches off the
trachea are called
bronchi
What prevents the trachea from
collapsing?
rings of cartilage
The dome shaped muscle below
the chest cavity is called the
diaphragm
Alveoli in the lungs are connected to
the bronchi by a network of tiny
tubes called
a) arterioles
b) venules
c) capillaries
d) bronchioles
Inside the alveoli, carbon dioxide and
oxygen
a) are transported along microscopic
tubules
b) are exchanged between air and
blood
c) are produced inside cells
d) are exchanged for other gases
Humans breathe more rapidly during
exercise than before it because
during exercise the blood contains
1.an increased level of oxygen
2.a decreased number of red blood
cells
3.an increased level of carbon dioxide
4.a decreased amount of hemoglobin
Breathing is an involuntary process
controlled by the amount of ____
in your blood.
carbon dioxide
BRONCHIOLEA
CAPILLARIES

ALVEOLI
1. Identify structures
A, B and C.
2.Identify the process
that occurs in the
alveoli.
GAS EXCHANGE
3. What happens to
the blood pumped to
the lungs?
IT BECOMES
OXYGENATED

2. What process
exchange
occurs in this
structure?
3. Identify the blood
capillary
vessel surrounding
this structure.O2
4. Identify gas X.CO2
5. Identify gas Y.
6. Identify the
process that causes
diffusion
the movement
of
gases.
