Oxygen CellHi 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.

Welcome

Now we will begin our tour.

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.

JH

Here is a overview picture of the Respiratory System.

Just go to the next slide to seeit.

Where are we?

Nasal Passage

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.

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

MB

The Nose and MouthWhen 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 yourmouth/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.

MB

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 ringsof cartilage.” Without these rings your trachea might close off and air would not be able to get

to and from your lungs.MB

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

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 tubesand into your bronchiole. These tubes

keep getting smaller and smaller until theyfinally end with small air sacs (called alveoli).

But we will go there later…

Now we will head over to the alveoli and what happens when the

air finally makes it down there.

The Alveoli and Capillary Network

MB

The Alveoli and Capillary Network

Your alveoli are tiny air sacsthat fill up with air/oxygen when you

breath in.

Your alveoli are surrounded bymany 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, orout of your blood stream.

MB

Here is a closeup picture ofyour Alveoli

* A specialized thin layer of skin that oxygen and carbon dioxide can pass through.

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

Intro to

Diaphragm

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

Here is an experiment that you can try.

Respiratory Overview Review

CO2

JH

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 stem

Air 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

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.
