Here are some responses to the assignment questions: 1. General ways to minimize or prevent respiratory ailments include maintaining good hygiene, getting adequate rest, and avoiding exposure to pollutants and irritants. 2. To inform the public about the dangers of smoking and lung cancer, one could create educational materials highlighting the health risks and statistics, give presentations, or participate in advocacy campaigns. 3. Traffic aides and factory workers wear masks to filter out pollutants and particles in the air that could otherwise be inhaled and potentially damage the lungs over time with prolonged exposure. 4. Your breathing rate increases in crowded areas due to higher levels of carbon dioxide from many people exhaling in a confined space.

4. • Yawning happens when the body is
tired. A tired body slows down. It does not
readily get rid of metabolic waste. Thus, too
much carbon dioxide remains in the blood,
which, in turn, activates the breathing center.
• The body involuntarily opens the mouth wide,
takes in an enormous amount of air, and then
pushes out a large breath that expels a lot of
carbon dioxide.

5. Hiccups happen
when the
breathing center
activates the
diaphram to inhale
air, while the
epiglottis at this

6. Checking of Assignment
• Recall how many times you suffered
from colds. What do you do?
• Causes, symptoms, prevention and
treatment of common ailments of the
respiratory system

7. Presentation
• Each group will represent a common
ailment of the respiratory system and
report to the class the symptoms,
causes, prevention and treatment of
the ailment.

10. S A R S
Severe Acute Respiratory Syndrome – is a
corona virus infection and very contagious.
The symptoms are very high fever,
shortness of breath, dry cough, headache,
muscle pains, loss of appetite, sore throat,
fatigue, and diarrhea. There is no known
treatment for SARS.

11. COPD
Chronic Obstructive Pulmonary Disease,
is a lung condition usually caused by
smoking. People with COPD have difficulty
breathing. In the early stage of COPD,
they may feel breathless during physical
activity. Eventually, they have trouble
breathing even at rest.

12. COPD
The lungs’ airways are called bronchi, or
“branches.” They divide and spread
throughout the lung and end in tiny sacs.
In someone with normal lungs, these sacs
inflate upon the inhale and deflate upon
the exhale. In people with COPD, the sacs
don't work properly because they are
damaged (this condition is also known as
emphysema) or the bronchi become
inflamed (chronic bronchitis).

13. A tracheotomy is a surgical procedure in
which a cut or opening is made in the
windpipe (trachea). The surgeon inserts a
tube in the opening to bypass an
obstruction, allow air to get to the lungs, or
remove secretions. Tracheostomy refers to
the opening itself.

14. Application
How can you relieved from
the discomforts brought
about by these ailments?

15. Application
• A vital part in keeping the body healthy
and its immune response functioning at
peak efficiency: proper nutrition, healthy
amounts of good-quality drinking water,
adequate rest, regular exercise, and
stress reduction.
• All forms of air pollution have some
harmful effects on our respiratory system.
Prolonged exposure to carbon monoxide
can cause heart and respiratory disorders.
