One of the questions that many of my non-medical friends always ask me is: “Do smokers have particularly dark lungs?” The answer is yes, indeed. In children, the lungs are light red. As they grow, particles such as dust and carbon dust in the air are inhaled into the lungs and deposited in the lungs. In adults, the lungs become dark red or dark gray, and if you are a long-term smoker or live in a smoky environment, the lungs seen at the time of surgery are dumpling black. When you enter the chest cavity during surgery, you can visually see that most of the non-smoking lungs are very light in color and very elastic, mostly seen in non-smoking women, while the lungs of those men who have been smoking for a long time are indeed very black, such comparative pictures can be seen everywhere online and are also used in public service announcements for smoking cessation, here, I will not post pictures, or advise everyone to be health conscious and not to smoke as much as possible I’m not going to post a picture here, but I’d like to advise everyone to be health conscious and not to smoke whenever possible.
