Respiratory
Damage
The environmental polluting agents of air such as cigarette
smoke cause most damage to the RESPIRATORY TRACT. This is
easy to explain once we look at some fundamental notions
of respiratory anatomic physiological pathology.
People
inhale 15-20 times per minute on average i.e. 21,000-28,000
times per day equal to 7.5-10 millions times a year and
more than a half billion in a lifetime. Every day we breathe
in and out 15,000 litres of air i.e. five and half millions
litres per year, filtered through an alveolar surface of
70-100 square meters. By breathing in we convey to the alveoli
3,000 litres of O2, whereas by breathing out we take away
from the alveoli 6,000 litres of carbon dioxide (CO2).
It is
inevitable that harmful agents in the air will attack the
integrity of the respiratory tract. Each puff of smoke contains
at least 10 to the power of 15 i.e. 10 followed by 15 zeros,
an unimaginable number of oxidizing and irritating substances
that are responsible for damage to the respiratory tract.
Smoke
contains about 4000 damaging components which cause: nicotine
addiction, increases heart beat frequency, circulatory problems,
less nourishment for tissues, less oxygenized blood, skin
discoloration, hair loss, premature aging and a reduced
breathing capacity. These irritants also cause a build up
of: mucus accumulation in bronchi, chronic bronchitis, carbon
monoxide, emphysema, benzpyrene and other carcinogenic substances,
which increase the risk of cancer.
