3. Lung Diseases Affecting the Airways
Your windpipe (trachea) branches into tubes called bronchi, which in turn
become smaller tubes throughout your lungs. Diseases that can affect these
airways include:
• Asthma. Your airways are constantly inflamed and may spasm, causing
wheezing and shortness of breath.
• SYMPTOMS
• Chest tightness
• Coughing, especially at night or early morning
• Shortness of breath
• Wheezing, which is a whistling sound when you breathe out
4. • Chronic obstructive pulmonary disease(COPD).
With this lung condition, you can’t exhale the way
you usually would, which causes trouble breathing.
• Symptoms-Shortness of breath, especially during
physical activities
• Wheezing
• Chest tightness
• Chronic bronchitis. This form of COPD brings a
long-term wet cough.Is not caused by virus or
bacteria.
• Acute bronchitis.This sudden infection of your
airways is usually caused by a virus.
• Symptoms-Coughing with or without mucus
• Soreness in the chest
• Feeling tired
• Mild headache
5. Lung Diseases Affecting the Air Sacs (Alveoli)
Your airways branch into tiny tubes (bronchioles) that
end in clusters of air sacs called alveoli. These air sacs
make up most of your lung tissue. Lung diseases
affecting your alveoli include:
• Pneumonia. An infection of your alveoli, usually by
bacteria or viruses, that inflames air sacs which fill
with fluid.
• Tuberculosis. Pneumonia that slowly gets worse.
-caused by the bacteria Mycobacterium tuberculosis.
• Emphysema.A lung condition that causes shortness of
breath, alveoli are damaged. Smoking is the usual
cause. (Emphysema also limits airflow, affecting your
airways.)
6. • Lung cancer.Lung cancer is a type of
cancer that starts in the lungs. It has many
forms and may start in any part of your
lungs. It most often happens in the main
part of your lung, in or near the air sacs.
• Symptoms-A new cough that doesn't go
away
• Coughing up blood, even a small amount
• Shortness of breath
• Chest pain
• Bone pain.
