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.

5. Respiratory Intro
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.

9. Now we will begin our tour.
Welcome to…

10. This is where it all begins.
This is where the oxygen first
enters your body and also where
Carbon Dioxide leaves.
The Nose and Mouth

11. 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.

14. 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.

15. The Pharynx and 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.

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

18. 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).
But we will go there later…

21. Now we will head over to the
alveoli and what happens when the
air finally makes it down there.
The Alveoli and Capillary
Network

22. 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.

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

31. Diagram of Diaphragm

32. Here is an experiment that
you can try.Diaphragm Experiment

33. 1st you need a bottle that you can
sacrifice to
cut up.
2nd you cut the bottom of the bottle and put a
big balloon on the bottom.
3rd get a rubber cork ( make sure it blocks the
hole)and put a hole through it ( top to bottom).
Insert a thin tube into the cork and place a
balloon on the bottom of the tube.
4th make sure the thing is airtight.
Experiment Instructions

34. The Pharynx, or throat,
is located where
passages from the nose
and mouth came
together.
Air Passing over the
mucus membrane of the
nasal cavity is moistened,
warmed, and filtered
Inside the lungs the
Bronchi branch into
small tubes called
bronchioles
At the end of the
bronchioles are
bunches of alveoli,
air sacs, arranged
like grapes on a
stemAir enters the
trachea, or wind
pipe which leads
to and from the
lungs
The trachea divides
into two tubes called
bronchi
If one lobe is injured or
diseased, the other
lobes may be able to
function normally

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

36. Key Words Cont.
 Bronchi Tubes- Each tube (one per lung) splits up into many smaller
tubes called Bronchiole, like branches on a tree.
 Bronchiole- Keep splitting up until they reach your Alveoli.
 Respiratory Bronchiole- The air-tubes that are actually connected to the
Alveoli.
 Alveolar Duct- The final tube, which is part of the Alveoli, that leads to
the air-sacs.
 Alveolar Sac- Where the chemical change takes place and where blood
cells pick up oxygen and drop off carbon dioxide.
 Alveoli- Tiny air-sacs at the end of your Alveolar Duct. They fill up with
Oxygen and are surrounded by Capillaries.
 Capillaries- Tiny blood streams (around one cell wide) that surround your
Alveoli. They take Oxygen out of our Lungs and replace it with Carbon
Dioxide, which you later breath out.
 Diaphragm- The muscle membrane that helps you breath in and out by
changing the pressure in your chest cavity.
