The definition of respiration
• Respiration is the process which
food molecules are broken down
to release energy
• Respiration is the exchange
process of O2 and CO2 gases to
produce energy
RESPIRATORY ORGANS
Why we breathing through the
nose?
The advantages are:
• Dust and foreign particles are
trapped by the hair in the nostrils
• Air passes through the nasal is
warmed and moistened before it
enter the lungs
• Harmful chemicals may be
detected by the sensory cell in
the mucous membrane
The respiratory organs and their
function:
No
Organs
1. Nostril
Functions
Here air is exchange by
environment and the respiratory
organs
2. Nasal cavity As air passes through a nasal
cavity, it is warmed. Dust
particles are filtered out by fine
hairs. Mucus membranes lining
the nasal cavity add moisture to
the air.
The respiratory organs and their
function:
No
Organs
3. Pharynx
4. Larynx
5. Trachea
Functions
It is part of the windpipe, which
connects the mouth and nose
to the lungs.
It contains flexible boxes called
vocal cords.
It is the windpipe, which
connect the mouth and nose to
the lungs.
The respiratory organs and their
function:
No
Organs
Functions
6. Bronchiolus
It is the windpipe, which
connect the mouth and nose
to the lungs.
7. Lungs
Air exchange between the
lungs and blood in the
capillaries. Carbon dioxide
leaves the blood and diffuses
in to the air. Oxygen is
diffused from the air into the
blood.
Conclusion
Respiration is needed for
generating the energy that is
used for building and repairing
body tissues.
The lungs and the tubes leading
to them make up the respiratory
system
THE DISEASES AND DISORDER OF RESPIRATORY
SYSTEM
 EMPHYSEMA is a disease in which the alveoli in the lungs
lost their ability to expend and contract
 CHRONIC BRONCHITIS is a disease which too much
mucus is produced in bronchial tubes
 ASTHMA is a disorder of lungs in which there may be
shortness of breath, wheezing or couching
 LUNG CANCER is an uncontrolled division of cells
producing outgrowths or lumps of tissues. Apart from
lung cancer, smoking also increases the risk of cancers of
the mouth, throat, pancreas, kidneys and urinary
bladder.
