1.Lung structures.
The lungs are the main organs of the respiratory system and are responsible for gas exchange. It is made up of two lobes, each of which is further divided into lobules. The alveoli are the basic unit of gas exchange in the lungs, and their walls are thin and elastic, which facilitates gas exchange.

Smoking causes a lot of harmful substances to accumulate in the lungs, such as nicotine, carbon monoxide, tar, etc. These harmful substances can affect the gas exchange function of the lungs, leading to symptoms such as hypoxia and difficulty breathing. Long-term smoking also increases the risk of diseases such as lung cancer and chronic obstructive pulmonary disease.
3.Lung cleansing mechanisms.
The lungs have a certain ability to clean themselves. The surfactant in the alveoli maintains the stability of the alveoli and prevents alveolar rupture. At the same time, the cilia on the mucous membranes of the lungs sweep away harmful substances and excrete them from the body by coughing. However, smoking produces too many harmful substances that exceed the lungs' ability to clean, causing the lungs to turn black.

Blood circulation improves, the mucous membranes of the lungs are repaired, and ciliary function gradually returns to normal. Studies have shown that after 10 years of quitting smoking, the risk of lung cancer is reduced by half.

Although quitting smoking can restore the lungs to a certain extent, it does not mean that the lungs can completely return to the state before quitting. Because lung damage caused by smoking is irreversible, especially for long-term smokers. In addition, smoking increases the risk of cardiovascular disease, osteoporosis, and other diseases.
