Hi I am O2 ,you can call
me oxygen, and I will be your guide today.
I advise you keep all feet
and hands inside the ride at all times.

You may be asking, what is the
Respiratory system? Well, the
Respiratory system is the system that
helps you breath in and out, so
oxygen (02) can be pumped through
your body and carbon dioxide (CO2)
can be removed from the blood
stream. You must remember that the
Respiratory system is made up of
many different organs.

-Trachea
The Nose and Mouth
This is where it all begins.
This is where the oxygen first
enters your body and also where
Carbon Dioxide leaves.
MB
The Nose and Mouth
When the air comes into your nose it gets
filtered by tiny hairs and it is moistened by the
mucus that is in your nose.
Air can also get into your body through your
mouth/oral cavity but air is not filtered as
much when it enters in through your mouth.

The Pharynx and Trachea
Next we will head down to your pharynx
(throat) and your trachea (windpipe).
This is where the air passes from your
nose to your bronchi tubes and lungs.

(Throat)
Trachea
Your pharynx (throat) gathers air after it passes
through your nose and then the air is passed down to
your trachea (windpipe).

-Trachea
The Bronchi Tubes
and Bronchiole o
Trachea
Your trachea (windpipe) splits up into
two bronchi tubes.
These two tubes keep
splitting up and form your bronchiole.

MB
The Bronchi Tubes and
Bronchiole
These bronchi tubes split up, like
tree branches, and get smaller and smaller
inside your lungs.
The air flows past your bronchi tubes
and into your bronchiole. These tubes
keep getting smaller and smaller until they
finally end with small air sacs (called alveoli).

MB
We are here.
The Trachea
is held open
by partial
rings of
cartilage.
Bronchioles pass
air to and from
your alveoli.
Very thin cells line the
alveoli so that O2 and
CO2 can pass in and
out of the blood.
The Alveoli and Capillary
Network
Now we will head over to the
alveoli and what happens when the
air finally makes it down there.
MB
The Alveoli and Capillary
Network
Your alveoli are tiny air sacs
that fill up with air/oxygen when you
breathe in.
Your alveoli are surrounded by
many tiny blood vessels called
capillaries.
The walls of your alveoli (and capillaries) are
so thin that the oxygen or carbon dioxide can
pass through them, traveling right into, or
out of your blood stream.

Now we will look at the Diaphragm.
You might be wondering, what does the
Diaphragm do? The Diaphragm is an
important factor in breathing.

Diagram of Diaphragm
JH
Inhalation
Rib cage moves up and out
Diaphragm contracts
and moves down
Pressure in lung decreases
and air comes rushing in
MB
Exhalation
Rib cage moves down
and in
Diaphragm relaxes
and moves up
Pressure in lung increases
and air is pushed out
