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. In other words, I am
responsible for
GAS EXCHANGE!!!
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.

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.
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.
Pharynx
(Throat)
Mouth
Trachea
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
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).
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.

Here is a closeup picture ofyour Alveoli
and a Capillarysurrounding it.

Where are We?
We are here.
Diffusion
Oxygen
Carbon Dioxide
Membrane*
Capillary
* 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.
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!!
Carbon Dioxide leaves the body the way oxygen entered the body…

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.
