Transcript of contents that are in cigarettes

Smoking In what ways is tobacco smoke particularly harmful for women who are pregnant? What technologies are available to assist people who choose to quit smoking? What are examples of long-term and short-term effects of smoking? How can tobacco chemicals appear in other body organs such as the bladder, heart, and reproductive organs? Some technologies are
herbal methods
gum
patches
Nicorette inhaler Short term
-increase in blood pressure and heart rate, so the heart is working harder
- Blood flow to the hands and feet are reduced
-short term stimulations to the brain and nervous system
-some people have a smaller appetite
-foul breath
-stained teeth and finger
-annoying coughing
-reduce or loss of sense of taste or smell
-reduced immune systems (more colds and flues)
-many smokers often look older, earlier. So they seem to age faster
Long term
-respiratory infections such as pneumonia and chronic bronchitis
-Emphysema (irreversible, incurable, and sometimes fatal)
-vascular decease, coronary disease (which can lead to heart attacks)
-heart attacks
-all kinds of cancer
-vascular disease in the body’s extremities (hands, feet, arms and legs) which can lead to painful ulcers
Some ways that tobacco smoke is particularly harmful for who are pregnant is it could lead to:
A higher risk of having a miscarrage
A premature birth
A higher risk of sudden infant death syndrome (SIDS)
A low birth weight

Heart
The tobacco chemicals move into the bloodstream and the Heart pumps the chemicals through out the human body.
Analysis 1. list three harmful effects of smoking on the respiratory system and three harmful efects on other body systems

When a smoker coughs, it is an irritation in the respiratory system, which phlegm accumulates in the trechea. Tar is in cigarettes and when smoked the tar is coated in the throat to the lungs. Another effect in it could cause cancer in the lungs and other locations in the body.
There are also effects that harm other body systems. In the circulatory system, the nicotine flows through the bloodstream. It also effects the nervous system because drugs destroy brain cells.

2. Because smoking has clearly identified health risks, why do you think people smoke? Give at least two reasons.

Some people smoking to be 'cool'.
Others just want to try it out.
propaganda
stress
pure pressure

3. Identify at least two techologies developed to assist people who choose to quit smoking.

two technologies that were developed to help people who choose to quit smoking is patches and special gum.

Reproductive system Male and Female
decreased sperm count and movement
lowered sex drive
egg damage, irregular menstrul cycle and altertered hormone levels
early onset of menopause
increased risk of breast cancer
cancers of the cervix, penis and anus
Benzene (petrol additive)- A colourless cyclic hydrocarbon obtained from coal and petroleum, used as a solvent in fuel and in chemical manufacture - and contained in cigarette smoke.
A It known carcinogen associated with leukaemia.

•Formaldehyde
(embalming fluid)- A colourless liquid, highly poisonous, used to preserve dead bodies - also found in cigarette smoke.
•Known to cause cancer, respiratory, skin and gastrointestinal problems.

Ammonia
(toilet cleaner)•Used as a flavouring, frees nicotine from tobacco turning it into a gas
•Often found in dry cleaning fluids.
Acetone
(nail polish remover)•Fragrant volatile liquid ketone, used as a solvent, for example, nail polish remover
•Found in cigarette smoke.
Tar•Particulate matter drawn into lungs when you inhale on a lighted cigarette. Once inhaled, smoke condenses and about 70 per cent of the tar in the smoke is deposited in the smoker's lungs.
Nicotine
(insecticide/addictive drug)•One of the most addictive substances known to man, a powerful and fast-acting medical and non-medical poison.
•This is the chemical which causes addiction.
Carbon Monoxide (CO)
(car exhaust fumes)•An odourless, tasteless and poisonous gas, rapidly fatal in large amounts
•The same gas that comes out of car exhausts
•The main gas in cigarette smoke, formed when the cigarette is lit
Others•Arsenic (rat poison)
•Hydrogen Cyanide (gas chamber poison)
