1. THE
RESPIRATORY
SYSTEM

3. IT IS AN APPARATUS, A SET
OF DIFFERENT ORGANS.

4. •OUR CELLS USE
OXYGEN TO OBTAIN
ENERGY FROM THE FOOD
WE EAT.
HOW DOES IT WORK

5. AND PRODUCE CARBON DIOXIDE

6. THE RESPIRATORY SYSTEM ALLOWS
US TO TAKE OXYGEN FROM THE AIR
AND EXPEL CARBON DIOXIDE.
THIS PHENOMENON IS CALLED
RESPIRATION.

7. WHAT IS BREATHING?
OXIGEN IS VITAL FOR
OUR BODY’S CELLS.
THESE RESIDUES, AS
CARBON DIOXIDE, ARE
REMOVED BY THE
RESPIRATORY SYSTEM
THE ENERGY THAT
CELLS NEED TO LIVE
COMES FROM THE
FOOD WE EAT.

8. PARTS OF THE RESPIRATORY
SYSTEM
MOUTH
TRACHEA
DIAPHRAGM

9. THE RESPIRATORY SYSTEM IS MADE UP OF
1. AIRWAYS
- NOSTRILS
- PHARYNX
- LARYNX
- TRACHEA
- BRONCHI
2. LUNGS

10. NOSE
The nose is the door of the
respiratory system that allows us to
smell and also to feel the taste. It
has two holes called nostrils, which
are separated by a smale wall called
nasal partition.
The nasal partition is made of
cartilage and very thin chunk bones .

11. MOUTH
It´s what we use to
introduce air into the body,
along with the nose.

12. PHARYNX
The pharynx is a tube-
shaped structure that helps
breathing. It is located in
the neck and connects the
nose and the mouth with
both the larynx and the
esophagus. Air and food go
through it.

13. LARYNX
The larynx is placed in the
beginning of the trachea.
The larynx is a cavity
formed by cartilages and a
lump called The Adam’s
apple .
The vocal chords are in the
larynx. When the vocal
chords vibrate, they
produce the voice.

14. TRACHEA
The trachea is a pipe
formed by cartilaginous
rings, which keep it
always open.
It is divided into two
branches: bronchi and
bronchioles.

15. BRONCHIOLES
AND
BRONCHI
The bronchi are the pipes
in which the trachea is
divided. They penetrate
in the lungs, where they
branch out several times
to form the bronchioles.

16. DIAPHRAGM
It is a muscle that separates
the chest from the abdomen.
When we inhale it moves
down to increase the size of
the throracic cavity.
When we exhale it moves up
reducing the thoracic capacity
and pushing the gases towards
the mouth or the nose to
eliminate them.

17. LUNGS
The lungs are two
spongy organs of
pink colour that are
protected by the
ribs.
They are inside the
torax.

18. AIM
To carry oxygen to the body´s cells

19. RESULT
• Carbon dioxide is produced (it is toxic !), and
it must be eliminated.

20. Air Pollution
Clean Air is important. Give your lungs a break.
Lung Health & Wellness
When you can't breathe nothing else matters.
Look after those lungs.
Respiratory System
Discover what our breathing system looks like and
how it functions. Wear a clean pair.
Tobacco
Smoking is the biggest cause of preventable lung
disease. Your smoking hurts my lungs.
