How Smoking Cigarettes Affects Your Lungs??
Burning tobacco produces more than 4,000 chemicals, including nicotine, carbon monoxide, and tars. These chemicals can transform normal cells into cancer cells.
The Effects of Cigarettes to Your Lungs and Airways
Smoking causes significant changes in your lungs and airways. Some changes are sudden, lasting just a short time. Colds and pneumonia are examples of this. Other, more chronic changes happen slowly and can last a lifetime — like emphysema.
Here are some of the changes that happen in your lungs and airways when you smoke:
More mucus and infections:When you smoke, the cells that produce mucus in your lungs and airways grow in size and number. As a result, the amount of mucus increases and thickens.
Your lungs cannot effectively clean out this excess mucus. So, the mucus stays in your airways, clogs them, and makes you cough. This extra mucus is also prone to infection.
Smoking causes your lungs to age faster and hinders their natural defense mechanisms from protecting you against infection
Smoking inflames and irritates the lungs. Even one or two cigarettes cause irritation and coughing.
Smoking also can destroy your lungs and lung tissue. This decreases the number of air spaces and blood vessels in the lungs, resulting in less oxygen to critical parts of your body.
The lungs are lined in broom-like hairs called cilia, which clean the lungs.
A few seconds after you light a cigarette, cilia slow down in movement. Smoking just one cigarette can slow the action of your cilia for several hours. Smoking also reduces the number of cilia in your lungs, leaving fewer to properly clean the organ.
