Title: Comparison of healthy lungs and smoker's lungs Written by: duddy on Jul 12, 2013 (https://biology-forums.com/gallery/47/4_12_07_13_4_36_08.png) (https://biology-forums.com/index.php?action=gallery;sa=view;id=12473) Remember, people who quit smoking can have their lungs return to normal in about 10-15 years. Comments: Just like a textbook, always showing the worst case scenarios, aren't you? ;) Written by: bio_man on Aug 2, 2013 That's a major difference, can't believe they can actually function looking like that :-\ Written by: sci_expert on Jul 17, 2013 Duddy, I'm glad you posted this. I'm sure it will help put things in perspective for some people. Written by: doseofmegan on Jul 13, 2013 Thanks for posting this. My uncle needs to see this to believe it. I found an article online that outlines what happens once someone quits. The first day Within 24 hours, the carbon monoxide – which hinders the blood from bringing oxygen to your cells, tissues and organs – has been removed from your body, and the mucus and smoking debris will start to clear from your lungs, making breathing easier. First week After two days there is no nicotine left in your body, and your senses of smell and taste will have started to improve dramatically. After three days, you should start to feel more energised and your breathing will become easier. Three to five months Within around three months your circulation will have improved, and any cough or wheezing should have mostly cleared up. Compared to when you were smoking, your lung function should have increased by around 10 per cent. Five years After several years, your risk of long-term disease begins to fall. After five years, the possibility of a heart attack is roughly half that of someone who is still smoking, and after ten years free from smoking, your heart attack risk is that of a non-smoker, while your risk of lung cancer has been halved.
