Pollution In The Community
Review
How does the respiratory system work?
• Air
enters the nose where it is warmed,
moistened, and cleaned
• It then enters the trachea (or wind pipe).
The Epiglottis prevents food for entering
the trachea
• The trachea branches off into the bronchi
• Inside your lungs the bronchi divide into
many smaller branches called a bronchiole
• The tiniest bronchioles are called alveoli,
which are tiny one celled air sacs which
allows the transfer of Oxygen and carbon
dioxide
What health problems can our
respiratory system have?
•
•
•
•
•
Allergies
Bronchitis
Pneumonia
Tuberculosis
Asthma
What happens to your lungs when you
encounter harmful things like germs,
tobacco and allergens.
• Increased Mucus
• Narrowing of bronchi and
bronchiole
• Pus
• Swollen membranes
• Damaged alveoli
• Tumors
• Harmful gas exchanged instead of
oxygen
So… What are we going to do today???
• You know how the repertory system works
and what happens to the lungs when they
have problems
• Today, we are going to look more closely at
different lung problems related to the
community and how we can help our
community reduce the amount of lung disease
• Today we are about saving lives in our
community!
What is a community?
• Since people work and live in a community,
the health of their lungs often depends upon
the quality of air in the community, the
location of the community, the type of work
done in the community, and the attitude of
the people toward smoking.
• All of these factors will make a community
healthy or unhealthy, as far as the lungs are
concerned.
• Today you will be responsible for your own
learning and for teaching others what you
have learned.
• I will create 4 groups
• You will work with those members to read the
information about community lung hazards
• You will create a public service poster to
educate about that hazard
The four groups are…
