
Carbon Monoxide: Is a colorless, odorless,

The gas unites with the hemoglobin and
prevents it from carrying oxygen.


Cigarette smoke contains over 4,800 chemicals, 69 of
which are known to cause cancer.
About 8.6 million people in the U.S. have at least one
serious illness caused by smoking.
Secondhand smoke involuntarily inhaled by nonsmokers
is responsible for approximately 3,000 lung cancer
deaths annually.
Close to 393,000 people die annually from tobaccorelated diseases and approximately 1,100 kids become

Smoking

Effects on the lungs
How the circulatory system works
The Healthy Lung

Anatomy & Physiology
of the lungs.
Chronic Bronchitis

Chronic bronchitis: is
the inflammation and
eventual scarring of the
lining of the bronchial
tubes. As the cilia
become useless, tar
from cigarette smoke
builds up, which results
in coughing and
excessive mucus
secretion.
Pulmonary Emphysema

In emphysema, the
fine dividing walls
between the tiny air
sacs break. The sacs
balloon out to become
large pockets of air
with hard inflexible
walls.
Lung Cancer

Cancer is an area of
uncontrolled cell
growth that invades
the surrounding tissue
and destroys it. This
is due to the build up
of tar in the lungs.
