Smoking & Your Lungs
Look at these videos and BE AWARE!
There are over 4000 chemicals in a cigarette and 69 of them are approved that they cause cancer.

Three main ways smoking hurt your lungs
The Cilia (The thing that brushes the tiny dust floating around away from your precious lungs)
When the smoker breathes in the smoke of the cigarette, it goes through the esophagus and the windpipe. After that, it passes through the upper airways over the cilia. The tiny hair of the cilia is responsible for protecting the lungs disease by moving the mucus out of the lungs. When we smoke too much, the mucus mixed with damaging toxins get clogged in the lungs, at this point, cilia can no longer move. This increases the chance of the smoker getting lung cancer or COPD (Chronic Obstructive Pulmonary Disease) (Green).
The Alveoli (The thing that transfers oxygen from the lungs to the red blood cells in your circulatory system)
The smoke continues to divide continuously through two different types of lungs, the left and the right lungs, then into the smallest passages of the lungs which is known as the alveoli. The alveoli are the final branching of the respiratory system. They are also are the air sacks that transfer oxygen into our blood which could be compared to tiny balloons. Over a period of time, the cause of smoke make the alveoli to turn less elastic. It makes it more difficult for the alveoli to absorb oxygen and removes carbon dioxide from the lungs when it loses the elasticity. This could be the reason answer to what causes shortness of breath when start to smoke (Green).
The smoker have a hard time exhaling when the elastic recoil is destroyed. This difficulty leads to an excess of the carbon dioxides in the lungs which eventually going to fill the lungs with carbon dioxide. This destruction leads to emphysema (Greeen).
3 main harmful chemicals in cigarettes
What is harmed
How is it harmed
Makes the alveoli less elastic causing shortness of breath
Hinders the ability of the pancreas to
Attaches itself to red blood cells like oxygen does, causing oxygen deprivation
Paralyses it, causing mucus to not be moved out of the lungs, increasing the risk of cancer or COPD
How does smoking causes bronchitis and emphysema?
First of all, what does it mean by chronic bronchitis and emphysema?
Chronic bronchitis and emphysema are well know lung disease cause by smoking which will give symptoms like cough and then develop into short of breath. It generally happens together, thus it is sometimes also called as chronic obstructive airways disease (COAD) or chronic obstructive pulmonary disease (COPD). 'Chronic bronchitis is 7 times more common than emphysema' ("Chronic Bronchitis & Emphysema"). Doctors say that if smoking is stopped there is less chance to develop the disease or even stop the disease from getting worse. In Ireland, 100,000 people are in pain with bronchitis and emphysema. Conversely, there is only minor public awareness of these disease. It is easier to look inside the lungs when this disease passes through and invades the lungs("Chronic Bronchitis & Emphysema").
In chronic bronchitis, the branches of the tree, or bronchial tubes, are affected. Bronchitis means inflammation in the bronchial tubes, and chronic means that the inflammation has been there a long time. When inflamed, the walls of the bronchial tubes produce thick material called mucus. The person tends to cough up this mucus every day, especially in the morning. The mucus can block the bronchial tubes, making it more difficult to breathe in and out. The mucus can sit in the tubes for a long time, and become infected with bacteria. This is why people with chronic bronchitis get frequent chest infections. After long-term smoking, the walls of the bronchial tubes can become thicker. This narrows the tubes, making it more difficult to breathe ("Chronic Bronchitis & Emphysema").
Emphysema may be present without drawn bronchitis and is a result of damaged air sacks in the lungs. This causes them to lose their ability and potential to expand and contract normally. This also causes to reduce it's elasticity.Moreover, in emphysema, the leaves of the tree, or alveoli, are slowly destroyed, so that oxygen cannot be extracted from the air inhaled. The more alveoli damaged, the worse the problem, and the greater the degree of breathlessness ("Chronic Bronchitis & Emphysema").
Smokers vs. non-smokers
The toxins that we introduce to the body which harms the phagocytes. This makes them trying to defend the toxins that are introduced to the body to our systems. By increasing the toxins and bacteria or virus would make the body overworking because they are trying to defend from both toxins and microbes. The body goes to attack the toxins first because they are more abundant which leaves the bacteria or virus to increase for a short while. This is one of the reasons why it takes longer for smokers to get over their infections.
Less attention your body pays to what enter through your lungs because the longer you smoke. The body defends less illness, toxins, and growth as the time goes by which eventually the tissues begin to die after being covered in tar and other toxins and poisonous chemicals. This makes the body reduces the ability to transport units to fight and defend infections. The body kills the cells and slowly shut down the blood vessels when you smoke. Osmosis only works if the cell membrane is in good condition or otherwise, you'll either let too much through or none at all.
