Answer 1

Tar (not nicotine)

Question 2

withdrawl from tobacco

Answer 2

is the same as withdrawl from nicotince since nicotine is the addictive substance in tobacco.

causes irritability and poor concentration

raises smoker’s physiological althitude

Question 3

smokers have increased risk of

Answer 3

urinary, pancreatic and bladder cancer

blockag of small blood vessels, therefore causing myocardial infarctions and stroke

Question 4

smoking 3 or 4 cigarrents in an hour can reduce your…

Answer 4

reduce tolerance to hypoxia due to slight carbon monoxide poisoning

meaning hte cardiovascular system is unable to take up enough oxygen to the body

Question 5

what does Tar cause

Answer 5

the brown sticky substance deposits in the lungs

stops alveoli from performing their natural function

clogs up the hairs/cilia in the lungs that clearn it

cancer in organs like bladder, lungs as it’s a carcogenic substance

Question 6

What does nicotine do

simulates adrenaline which increases hear rate and blood pressure

Question 7

when you smoke you lose capacity to transport oxygen via haemoglobin. How much capacity do you lose from 1 pack a day?

Answer 7

5 - 8%

Question 8

the physiological altitudle of a chronic smoker at sea level

and in cabin altitude of tranport plane (8000 ft)

Answer 8

5000 ft approx
at sea level

5000 + 8000 = 13000 ft

Question 9

flying at pressure altitude of 10,000 ft
a chronic smoker has an oxygen content in the blood equal to ?

Answer 9

at sea level, usually the physiological altitude is 5000 ft

Even if he is flying at pressure altitude of 10,000 ft, the cabin pressure altitude is usually 8000 ft

therefore. 5000 + 8000 = 13,000 ft

Question 10

carbon monoxide can cause

Answer 10

hypoxia at lower altitudes, which may lead to reduction of time useful to consciousness TUC
