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. In other words, I am
responsible for GAS EXCHANGE!!!
Respiratory Intro
Nasal Passage
Where are we?
Here We Go!!!
Tongue
Pharynx
Bronchi Tubes
Alveoli (air-sacs)
Thin-walled blood vessels
called capillaries
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. JH

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.
Your sinuses also help out with your
Respiratory System. They help to moisten
and heat the air that you breath.
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.

Pharynx
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.
The Pharynx and Trachea
Mouth
Pharynx
(Throat)
Trachea
Your pharynx (throat) gathers air after it passes
through your nose and then the air is passed down to
your trachea (windpipe).
Your trachea is held open by “incomplete rings
of cartilage.” Without these rings your trachea
might close off and air would not be able to get
to and from your lungs.
The Bronchi Tubes and
Bronchiole Intro
Your trachea (windpipe) splits up into
two bronchi tubes. These two tubes keep
splitting up and form your bronchiole.
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).

Alveoli
The Alveoli and Capillary
Network
Your alveoli are tiny air sacs
that fill up with air/oxygen when you
breath 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.
Alveoli Picture
Here is a close
up picture of
your Alveoli
and a Capillary
surrounding it.

We are here.
The Trachea

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.
Oxygen
Diffusion
Carbon Dioxide
Oxygen diffuses
through the
membrane into the
blood stream.
Carbon Dioxide
diffuses through the
membrane and
enters the alveolus.

Capillary
* A specialized thin layer of skin
that oxygen and carbon dioxide
can pass through.
Cool pictures
So once I am in the alveoli, I enter the
blood vessel and leave to go to the
heart to get transported anywhere in
the body that needs me!!

Fun Facts
* At rest, the body takes in and breathes out about 10 liters of air each
minute.
* The right lung is slightly larger than the left.
* The highest recorded "sneeze speed" is 165 km per hour.
* The surface area of the lungs is roughly the same size as a tennis court.
* The capillaries in the lungs would extend 1,600 kilometers if placed end to
end.
* We lose half a liter of water a day through breathing. This is the water vapor
we see when we breathe onto glass.
* A person at rest usually breathes between 12 and 15 times a minute.
* The breathing rate is faster in children and women than in men.
