What does The
Respiratory System
do?
The Respiratory System is
the organ system that
breathes in oxygen and
exhales carbon dioxide.
The main organ are the
lungs. It is the organ that
does so what I said at the
top. The diaphragm is the
muscle that contracts when
you breathe in and when
you breathe out it flattens
to push the air out after you
breathe. Now I will show
you in detail how the order
the Respiratory System
works.
The Path of The Respiratory System
The journey starts with the mouth or
nasal cavity. Remember, we can
breathe with either one. It goes by
the pharynx and larynx(they both
have to do with our voice box)and
go down the trachea, or windpipe.
They reach the lungs and go into
either one. They reach the alveoli
and there the oxygen-filled air is
used and is now is exhaled and is
full of carbon dioxide. As I said
earlier, it is pushed out by the
diaphragm as it expands to full size.
Your Epiglottis
The epiglottis is a little flap of muscle that
closes your trachea entrance so food doesn’t go
down your trachea. It doesn’t seem like a big
deal but it is. Another reason to be convinced of
it’s greatness is that is doesn’t seem you can get
sick of it(YAY!). I hope you think now it is a big
thing in The Respiratory System.
Trachea
The trachea is your windpipe
that air goes down into your
bronchi and into your lungs. To
let you know what it is made of,
it is a vertebrae; or bone. It is
quite important because if we
didn't have one how could we
breathe? That's up to you.
Bronchi
After the trachea comes
the bronchi. There are
probably two but if you
count the others that
branch off there are
probably more. It has
most likely the same job
as the trachea except this
reaches the lungs.
Lungs
The lungs are the most important
organ in the respiratory system. We
breathe in air and the air passes into
the trachea. It goes into either lung
through the bronchi and into the
alveoli. Then gas exchange
happens(I’ll cover that in my next
slide). Interesting, right? Quite right
if you said yes.
Alveoli
The alveoli are little parts in the lungs. In this area
Gas Exchange happens. That is when the air changes
from oxygen to carbon dioxide.
∙What is gas exchange?
Gas exchange is where the oxygen is taken to your
blood and cells. There it is used and the blood and
cells give it the carbon dioxide that comes after they
use the oxygen.
A Comparison of Healthy Lungs and
Non-Healthy Ones
Healthy Lungs
Unhealthy Lungs
The lungs are yes, the most important
organ in the respiratory system. This is a pair of
healthy lungs where this person never smoked
in his life. I am sorry for taking you off track,
but see this pair of clean lungs.
The lungs are very important but if you
treat them badly they might give you lung
cancer. They would get that cancer because all
that smoke pollutes your lungs and it can turn
all the parts in your lungs to die! My first reason
to keep lungs healthy is to NOT smoke or try to
not get second hand smoke.
How To Keep Your Respiratory System
Healthy
One way to keep it healthy
• Don’t Smoke.
Smoking is probably the dumbest
thing to do ever. It will take
about ten years for your lungs to
get pink again. I do not think it is
a good thing to do because it
wrecks up your lungs.
Another way to Keep them
healthy
• Exercise Daily
It may seem funny how can
exercising keep your lungs
healthy? Think about it. Your
lungs need a lot of air including
your body so if you exercise you
basically get more air intake.
If you don’t keep your lungs healthy….
This can possibly happen. I suggest that
you don’t smoke.
