2. Some possible lung disorders
asthma
acute bronchitis
chronic bronchitis
cystic fibrosis
emphysema
lung cancer
pneumonia
These two are chronic obstructive pulmonary diseases (COPD)
These are caused by smoking…
AND secondhand smoke…
3. chronic bronchitis
• chronic (long-lasting) inflammation of the bronchi
• persistent cough that produces phlegm and
mucus
Symptoms: Causes:
cough
tobacco smoking
shortness of breath (most common cause)
wheezing (deep breathing)
pneumoconiosis
chest pain (a disease caused by
the inhalation of dust)
fever
fatigue
malaise (feeling sick)
4. some factors increase the risk of chronic
bronchitis…these are:
age over 45 years
air pollution
allergic reaction to
animal dander
dust particles
pollen
fumes from chemicals or gases
jobs working with livestock, grain, textile, or coal
preexisting lung disease
respiratory infection
secondhand smoke
smoking
5. prevention:
getting pneumococcal and annual flu vaccines
washing hands (good hygiene)
NO smoking
AVOID secondhand smoke
taking medicine as prescribed…even WITHOUT
symptoms
6. emphysema
• a long-term, progressive disease
• destroys the lung tissue around the alveoli
panlobular emphysema
panacinar emphysema
acinus - refers to a cluster of cells
The that resemble a berry shape

expanded
Occurs mostly in the upper lobes
9. other types of emphysema
congenital lobar emphysema
paraseptal emphysema
10. lung cancer
uncontrolled cell growth in tissues of the lung
if left untreated, metastasis may occur
metastasis-spread of a disease from an organ/part to
another
11. Symptoms of lung cancer
dyspnea (shortness of breath)
hemoptysis (coughing up blood)
chronic coughing
wheezing
chest pain
cachexia (weight loss)
fatigue
loss of appetite
dysphonia (hoarse voice)
dysphagia (difficulty swallowing)
12. causes…
smoking
radon gas
radon- an element
odorless
tasteless
asbestos
a set of six naturally occurring silicate materials
silicate materials - make up the largest and most
important class of rock-forming minerals
viruses
13. Thanks for listening…
P.S. point taken…don’t smoke
unless you want to end up
coughing all day…
