What is Respiratory System?
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.
You may be asking, what is the Respiratory system?
Respiratory Intro
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.

Here is a overview picture of the Respiratory System.
Just go to the next slide to see it…

What are the components of Human Respiratory System?

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.

Pharynx

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 Mouth
When the air comes into your nose it getsfiltered 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
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
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… MB

Now we will head over to the alveoli and what
Happens when theair 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.

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

TYPE s OF BREATHING
CHEST BREATHING
(among bone rib muscular)
INSPIRATION: The ribs to be sure that the muscle among bone chest cavity, chest cavity becomes larger for that cause the pressure in the chest cavity becomes smaller in comparison to the pressure external so that oxygen-rich air outside the entrance.
EXPIRATION : phase relaxation or muscle some of the ribs return to the opening position is followed by a decline in the ribs so that the chest cavity becomes smaller. Because of this, the pressure inside the chest cavity will become larger than the external pressure, so air in the chest cavity is rich in carbon dioxide out.
ABDOMINAL BREATHING
(includes the diaphragm muscle)
INSPIRATION : This phase of the diaphragm muscle contraction and the position become horizontal, chest cavity becomes larger, for that causes the pressure in the chest cavity becomes smaller in comparison to the pressure outside so that oxygen-rich air outside the entrance.
Expiratory : This phase is the phase diaphragm muscle relaxation or return to its original position that utilized by a decline in the ribs so that the chest cavity becomes smaller. As a result, the pressure inside the chest cavity becomes larger than outside pressure, so air in the chest cavity is rich in carbon dioxide out.
