Diseases caused by Smoking

Question 1

Heart disease

Answer 1

• smoking causes a person’s arteries to become blocked.

- This prevents blood flowing properly, and can cause a HEART ATTACK or STROKE.

Question 2

Lung disease

Answer 2

-Chemicals in tobacco smoke affect the alveoli in your lungs.
-Their walls become weakened so they do not inflate properly when you inhale.
-They may also burst during coughing.
This reduces the amount of oxygen that can pass into the blood, making the person breathless.
-This disease is known as EMPHYSEMA.

Question 3

Respiratory infections

Answer 3

• Chemicals in tobacco smoke stop the cilia (tiny hairlike structure in windpipe lining to protect the air passage) from moving.
• This allows mucus to flow into your lungs, making it harder to breathe and often causing infection.
• Smokers cough this mucus up, which can damage the lungs further.
