This is our Pt in science and computer. I want to share this presentation to all of you to give some information. ^_^

1. Respiratory System

2. What is Respiratory
System?
How does it works?

3. Respiration is the
process of taking in
oxygen and
breathing out
Carbon dioxide

4. Breathing measurement
•We breathe about 20,000 daily
•If you’re already 70 years old,
that’s about 700 million breathe

5. The Airway
The Lungs
The muscles of respiration
3 Major Parts of Respiratory system

6. The Airway
The airway, which
includes the nose,
mouth, pharynx, larynx,
trachea, bronchi, and
bronchioles, carries air
between the lungs and
the body’s exterior.

7. The Nasal Cavity
•The term nasal cavity refer to
the two sides of the nose
combined as one.
•Exchanges air during inhaling
and exhaling warms,
moisturizes and filters inhaled
air

8. The Pharynx
•The Pharynx transport air back
and fort between the nose and
the trachea
•Commonly called as the throat
or being referred
•It serves as a pathway in the
process of swallowing

9. The Larynx
•Makes speech possible
•It manipulates speech
and volume
•The skeleton of the
Larynx contains 9
cartilage
•Also known as the
vocal chords, it controls
sound production

10. The Epiglottis
•It closes off trachea when
swallowing
•A flap of cartilage at the
root of the tongue
•It is made up of elastic
cartilage and covered with
mucous membrane
•It prevents food going to
the trachea

11. The Trachea
•Transport air back and fort
to the pharynx and bronchi
•Also known as ‘’Wind
pipe’’
•Tube like passage which
delivers wind to the
bronchi

12. The Bronchi
•Transport air from the
trachea to the lungs
•These airways then branch
into smaller pieces as they get
into the tissues of lungs
•The bronchiole terminates
into the alveoli

13. The Lungs
The Lungs act as the
functional units of the
respiratory system by
passing oxygen into
the body and carbon
dioxide out of the
body.

14. The Alveoli
•Air sacs that
exchanges gases with
the pulmonary
capillary blood

15. The muscles of respiration
The muscles of
respiration, including the
diaphragm and
intercostal muscles, work
together to act as a
pump, pushing air into
and out of the lungs
during breathing.

17. Diseases and Prevention
of Respiratory System

18. Asthma
Asthma is a chronic (life
time) disease that
makes your lungs very
sensitive and hard to
breathe. Asthma can’t
be cured, but with
proper treatment,
people with asthma can
lead normal, active
lives.

19. Lung Cancer
Lung cancer is cancer that
starts in the lungs. Cancer
is a disease where cancer
cells grow out of control,
taking over normal cells
and organs in the body.

20. Pneumonia
Pneumonia is swelling
(inflammation) of one or both lungs
that is usually caused by an infection.
Many different germs can cause
pneumonia, including bacteria,
viruses, and fungi. When you breathe
in these germs, they can settle in the
air sacs (alveoli) of your lungs. Deep
in your lungs, the germs may grow
and overcome your body's normal
defenses.

21. Prevention Respiratory
Problems
• Wash your hands often, especially when you are around
people with colds.
• Keep your hands away from your nose, eyes, and mouth.
These are the places where viruses are most likely to enter
your body.
• Do not smoke or use other tabacco products. Smoking
irritates the mucous membranes of the nose, sinuses,
and lungs, which may make them more susceptible to
infections. For more information, see the topic Quitting
Smoking.
