3. Oxygen Cell 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.

4. 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 (02) can be pumped through your body and (CO2) can be removed from the blood stream. You must remember that the Respiratory system is made up of many different organs. JH

5. Where are we? Nasal Passage Here We Go!!! Tongue Pharynx Bronchi Tubes
Alveoli (air-sacs)
Thin-walled blood vessels called capillaries
Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood.
Bronchioles pass air to and from your alveoli.
The Trachea is held open by partial rings of cartilage.

8. Welcome The Respiratory System Now we will begin our tour. Welcome to…MB

9. The Nose and Mouth This is where it all begins.
This is where the first
enters your body and also where
leaves. MB

10. The Nose and Mouth When the air comes into your it gets
filtered by tiny hairs and it is moistened by the
mucus that is in your nose.
Your 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
/ but air is not filtered as
much when it enters in through your mouth. MB

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

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

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

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

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

21. The Alveoli and Capillary Network
Your alveoli are tiny air sacs
that fill up with air/oxygen when you
in.
Your alveoli are surrounded by
many tiny blood vessels called .
The of your alveoli (and capillaries) are
so thin that the oxygen or can
pass through them, traveling right into, or
out of your blood stream. MB

and a Capillary

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

26. Diagram of Diaphragm JH

27. Here is an experiment that you can try.
Diaphragm Experiment JH

28. Experiment Instructions
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.
Experiment Instructions
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. JH

29. Respiratory Overview Review
CO2
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
The Pharynx, or throat, is located where passages from the nose and mouth came together.
Respiratory Overview Review
At the end of the bronchioles are bunches of alveoli, air sacs, arranged like grapes on a stem
Air enters the trachea, or wind pipe which leads to and from the lungs
If one lobe is injured or diseased, the other lobes may be able to function normally
The trachea divides into two tubes called bronchi JH

30. Fun Facts * The lung is slightly larger than the left.
* At rest, the body takes in and breathes out about liters of air each minute.
* The lung is slightly larger than the left.
* The highest recorded "sneeze speed" is 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 and women than in men.
