(1) Smoking & your lungs
 * How many chemicals in cigarettes?
 * Over 1000 known chemicals in cigarettes, these includes tar, carbon monoxide, sulphur dioxide, nicotine an d even small quantities of arsenic and plutonium.
 * There are over 4,000 different kinds of chemicals in cigarettes. 51 out of 4,000 of them are known to be carcinogenic. Carcinogen causes cancer.

Tobacco: It is the main ingredient (toxic material) in the cigarette. It is a green plant that grow in warm climates (summer) that is mostly grown by farmers legally. Fertilizers are added to make the soil richer and to make the insecticides to kill any unwanted insects and bugs that eat the tobacco plant.

** Chain Smoking: ** Chain smoking is what you can call "being addicted". Smoking cigarettes one after another and not stopping can cause serious harm to the lungs. There are tiny little hairs inside the lungs known as cilia that get rid of the mucus. Smoking one cigarette does not have enough nicotine to damage the cilia, however, chain smoking can build up enough toxic materials to damage and destroy these hairs. When this situation arises, the lungs can not get rid of all the toxic chemicals and eventually destroy them.
 * Three main ways smoking hurts your lungs
 * Smokers inhale tobacco smoke into their lungs, which irritates the air passages. This finally produces mucus, subsequently developing into chronic bronchitis. First, the smoke passes through your esophagus and then over something called cilia. Cilia are small hairs on the airway that protect the lungs from infection by moving mucus out of the lungs. When smoke passes over it, they can eventually be damaged to the point where they stop moving. Because the mucus is not moved, it can get mixed with toxins, increasing the chance of getting cancer or COPD (a lung disease making it difficult to breathe). The second thing that happens, is that the smoke eventually passes into all the small alveoli, the smallest passages of the lungs. They are the air sacs that transport oxygen into the blood. The smoke causes the alveoli to become less elastic, making it harder to absorb oxygen and remove CO2. This causes shortness of breath. The third effect it can have, is that also makes the actual lungs less elastic. Because they have less elastic recoil, the lungs have a harder time breathing out, filling the lungs with CO2. This can lead to emphysema (a type of COPD which involves destruction of the lungs) (The other form is chronic bronchitis)
 * ** Lung Elasticity: ** Smoking cigarettes can harm your lungs by exterminating the bendy recoil of your lungs. This can be a problem because it can cause the smoker hard to inhale and exhale breathing. Once hard to exhale while breathing, your lungs full up with Carbon Dioxide. This hardening of lungs can lead to emphysema.

 * Why are smokers more likely to develop lung infections than non-smokers? (Complete Bio Section 4.3)
 * 1) Carcinogens: Cause or aggravate cancer
 * 2) TSNAs: Tobacco - specific N-nitrosamines are known to have carcinogens present
 * 3) Benzene: Can be found in pesticides and gasoline, present in high levels in cigarettes
 * 4) Formaldehyde: Chemical used to preserve dead bodies
 * 5) Arsenic: Commonly used in rat poison
 * 6) Cadmium: Toxic that is used in batteries
 * 7) Ammonia: Commonly used in cleaning products and fertilizers
 * 8) Carbon Monoxide: Present in car exhaust
 * 9) Hydrogen Cyanide: Used to kill people in the gas chambers during World War II
 * 10) Nicotine: A poison used in pesticides

 * Explain how smoking causes bronchitis and emphysema
 * Bronchitis and smoking go hand in hand. When you breath, the airway goes down your throat and into your trachea, which is the beginning of your lungs. It forms two passage ways, one is the bronchi. These passage ways helps expand and contrast your lungs. With each breath you take your lungs fill with much needed oxygen. Smoking irritates your lining with the trachea and bronchi. When this happens, they swell up and mucous. The mucous actually clogs up the bronchi, making it more difficult to breathe. Basically, when you smoke, chemicals within the smoke irritate your bronchial tubes. Typical symptoms for bronchitis are cough, lack of air, mucous, and chest discomfort.

 * Emphysema
 * The more you smoke, the more damage occurs, the closer this damage becomes irrepearable. This can lead to emphysema which is a chronic lung disease. As the smoke is inhaled deep into the lungs, it leaves behinds pieces of chemical. These chemicals stay in the lung cavity and immediately start the damaging proccess. The chemicals destroy a hairlike cilia which keeps air passage from any mucus build up. This leads to extra mucus. This build up of mucus narrowes the air passageways. When these air sacs are punctured, they have a hard time seperating the oxygen from the carbon dioxide. Lack of proper oxygen also leads to organ damage. As emphysema worsens, the lungs lose elasticity and it is very hard for the smoker to take deep breaths. for example: A non smokers lungs would be like a inflated balloon while a smokers lungs would be all soft unflated. This is how Emphysema is caused. As the disease progresses the lungs get more and more damage and it is harder to breathe. Emphysema is uncurable. The smokers only choice is to quite to get any relief at all.
