Smoking

and risks to the lungs

Note: DON’T copy EVERYTHING :]

Some possible lung disorders

asthma acute bronchitis chronic bronchitis cystic fibrosis emphysema lung cancer pneumonia

These are caused by smoking… AND secondhand smoke…

These two are chronic obstructive pulmonary diseases (COPD)

chronic bronchitis

• chronic (long-lasting) inflammation of the bronchi• persistent cough that produces phlegm and

mucus

Symptoms: cough shortness of breath wheezing (deep

breathing) chest pain fever fatigue malaise (feeling sick)

Causes: tobacco smoking (most common cause) pneumoconiosis

(a disease caused by the inhalation of dust)

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

prevention:

getting pneumococcal and annual flu vaccines washing hands (good hygiene) NO smoking AVOID secondhand smoke taking medicine as prescribed…even WITHOUT

symptoms

emphysema

• a long-term, progressive disease• destroys the lung tissue around the alveoli

panacinar emphysemapanlobular emphysema The entire,

respiratory acinus from the respiratory bronchiole to the alveoli is expanded.

acinus - refers to a cluster of cells that resemble a berry shape ex. alveoli centriacinar emphysimacentrilobular emphysima The respiratory bronchiole is expanded Occurs mostly in the upper lobes

So what are the symptoms of

emphysema?

shortness of breath (on exertion) (exerting force)

which eventually leads to rapid breathing…

expanded chest

trouble coughing

lowered amount of phlegm

MAY loose weight

MAY develop a “barrel chest”

and the cause?...

tobacco smoking

long-term exposure to

air pollution

smoke

genetic factors

P.S. emphysema is…

slow to progress PERMANENT and IRREVERSIBLE

other types of emphysema congenital lobar emphysema paraseptal emphysema

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

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)

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

Thanks for listening…

P.S. point taken…don’t smoke unless you want to end up coughing all day…
