lung cancer.

what smoking can do to you.

Smoking is similar to digestion, but instead of digesting what you take in you in-digest, what goes in your body when you smoke stays in it. i quote: "Your body takes in a large amount of chemicals and carcinogens with each puff". Our organs and the blood in our body aren't made to handle all of the chemicals that make up a cigarette. Smokers often cough because of the tiny hairs in their lungs (cilia), are made to bronchial tubes and lungs of nasty foreign matter. They are one of the cleaners in your body, and smoking can result to destroying them. If the cilia you don't end up killing wake up after you start smoking, they start sweeping and make you cough because you could feel the cilia in your lungs working again. Deep inside your lungs, smoking could kill or damage the small alveoli that make up your lungs, one by one or some at a time. A lot of what is inhaled turns into tar, I quote; "Only about 30 percent of cigarette tar is sent back into the air through exhalation -- the rest sticks to your throat and lungs like saltwater taffy." apart from being disgusting tar can kill healthy lung cells. "A pack-a-day smoker ingests a full cup of tar into his or her lungs every year."

smoke can also cause arrhythmia, which makes your heart have irregular heart beats during the day.

What the government/people are doing to prevent lung cancer and smoking.

Lung cancer is common because of cigarette smoking.

The Australian government has been doing many things to prevent lung cancer from affecting people in our country. Things like putting gruesome photo's on the cigarette packets, showing the type of sicknesses and illnesses that would happen if you smoke too much.

Teachers, principals and school departments etc. Are all encouraged to teach school children and especially teenagers that it's not a good idea to smoke, the rules and consequences about it, how it can make a big impact to your life. If you teach them while they are young, and before they do it; then they would likely think twice about smoking.

There are also different types of advertisements to try and influence smokers, and encourage them to quit. Explaining on t.v that quiting is possible with a simple phone call. (For eg. Quit-line)

There is a ad on TV that shows air-sacs deflating one by one because a cigarette is burning them up, it is meant to represent your lungs.

People are taught to value their life more than a addiction, sadly some are not affective and people are still buying cigarettes, even now some have lost their lives or about to lose them.

what i would do to prevent lung cancer.

The most common thing that causes Lung cancer as we all know is Smoking cigarettes. If i could, and if i ruled the world i would stop cigarettes from existing, shops won't be able to sell it, there will be no such thing as smoking. If people smoke, i will make them pay $800 for one cigarette so less people could afford it and sell it to rich people for a billion dollars for just one. Hardly anyone will get lung cancer this way considering it would either not exist or it will be not affordable! However, if someone does chooses to smoke, they would get broke and not be able to buy anymore and would be bankrupt/poor.

Lung cancer.

Lung cancer is cancer in some of the cells in any parts of your lungs. it mainly starts in cells lining an organ called carcinoma. I quote; " the tissue that forms the base of the skin and the lining of the body’s inner surfaces"

There are different types of lung caner, the two main/common ones are called small cell carcinomas and non-small cell carcinomas. Lung cancer can vary depending on what cell is affected.

Small cell carcinomas:

Small cell carcinomas are also known as oat cell carcinomas because of it's shape. They are the cause of 15% of Lung Cancers. The cause of this particular Lung cancer is strongly because of cigarette smoking. Sadly, it spreads early and causes symptoms i quote: "so it's often already spread at the time of diagnosis."

Non-small cell carcinomas

Cells are 'building blocks' of our body, humans are made out of millions of cells which make up organs in our body. Different cells are made for different functions and there are many of them.

There is a part called the 'chest cavity' (thorax) found below the neck and shoulders, it is an area enclosed by the ribs. In the lower part there is the diaphragm, a wide, thin, dome of muscle found above the waist. Below that is the abdomen. I quote: "Non-small cell carcinomas include squamous cell carcinoma, adenocarcinoma large cell carcinoma, and bronchiolo-alveolar cell carcinoma." Squamous cell carcinomas usually damage cells that line the bronchi.

Causes of lung cancer.

It is estimated that around 90% of lung cancer is caused. Lung cancer mainly occurs in adults with ages 40-70years who would've probably smoked around 20 years. Some may have even started when they were teenagers.

Passive smoking, which is breathing in someone else's smoke. Eg. If you walk past a smoker or lives with someone who smokes daily in your main environment and breathe in their smoke, can also cause lung cancer and other diseases, as well as children and babies if their parents smoke around them near by.

i quote: "More than 2,300 Victorians are diagnosed with lung cancer each year." Lung cancer is the most common death in Australia for men and 2nd for woman.

I quote: "Two layers of thin membrane surround the lungs" this is called the pleura, it lines the chest wall and covers the lungs. The inner layers are stuck to the lungs and the outer; lines the chest wall and diaphragm. Between the layers is a space (mostly empty) called the pleural cavity. The two layers of the pleura are lubricant and smooth so that your lungs can move smoothly against the chest wall as you inhale and exhale.

What are alveoli? Why are they important?

When we breathe in, air goes through our mouth or nose, down our wind pipe (trachea) and into our chest. I quote: "The windpipe branches into 2 bronchi, one going to the left and right lung." The bronchi is similar to a tree because it branches many times to form smaller bronchi and then to even smaller tubes called bronchioles. I quote: “These tubes progressively branch 22 additional times to form more than 100,000 smaller tubes” Each one of the bronchioles turns into tiny, bubble-like air sacs called alveoli. It's the alveoli which makes the lungs in our body spongy.

Alveoli are small, hollow air sacks found everywhere on both lungs it is important because oxygen and carbon dioxide exchange through the capillaries (very small blood vessels) in them and it helps us breathe in and breathe out.

Each one of the alveoli receives blood from the circulatory system; it replaces carbon dioxide with oxygen. I quote: “The circulatory system then delivers the oxygen to cells throughout the body, bringing more wastes back to the lungs.” The smallest airways end in alveoli’s.

There are aprox. 300 million to 400 million alveoli in each lung. They are 0.3 mm in diameter.

The difference between alveoli and our lungs is that our lungs are two big organs that oxygen goes through and carbon dioxide goes out off, alveoli is what our lungs are made out of.

What are lungs? Why are they important?

Lungs are one of the many organs in your body, and like the organs, they are important and has a particular function which helps us survive. The lungs in your body are found in your chest; they are very large and take up most of the space in it. You have two lungs- the left one is a bit smaller than the right so it could make room for the heart. Your lungs are protected by your rib cage; it is connected to your spine and goes around your lungs to keep them safe. At the bottom of it there is a ‘dome-shaped’ muscle called the diaphragm. It works with your lungs to allow you to inhale (breathe in) and exhale, (breathe out). They work with the respiratory system; they also help with speaking every time you breathe in or out. The surface of the area of the lungs are gigantic it is said to be larger than a person’s skin.

Lungs are also important against the body’s defence to illnesses/sickness etc. I quote; “While the nose is the first line of defence against inhaled harmful materials, the lungs provide the second line of defence.” Small particles that are inhaled through the nose like pollution, smoke and bacteria pass through our nose or mouth and lodge in our lungs.
