Does our body fully heal after quitting smoking?

Cigarette smoke can have wide-ranging health effects on the body, and the lungs and airways are two of the hardest-hit areas.Stopping smoking is one of the best decisions you can ever make for your health. After quit smoking a big question come to our mind..
Does our body fully heal after quitting smoking?
Norman Edelman, chief medical officer of the American Lung Association, explains--When you quit smoking, the inflammation in the airways goes down. The little hair-like projections in the airways that we call cilia — which are paralyzed by smoke — begin to work again. So the lungs will get better in weeks to months. Breathing will get better. In the days to weeks after quitting, former smokers will notice that they have less shortness of breath when they exercise.

 The body is very good at repairing some of the damage to lung cells and tissues caused by smoking, but not all of the damage is reversible. If you've been smoking a long time and have developed  chronic obstructive pulmonary disease, which includes chronic bronchitis or emphysema, the lungs never totally heal.Emphysema is a disease in which the walls of the fine air sacs of the lung . So tiny little air sacs become bigger ones  and they're less efficient in transporting oxygen. The lung can't grow new walls for these air sacs. The lung loses tiny blood vessels and can't grow new ones. So that's permanent.
If your attempts to stop smoking don't succeed the first time, it is never too late to try again -- even if you have chronic obstructive pulmonary disease (COPD) or emphysema. The destroyed lung issue cannot be replaced, but you can avert further damage by quitting smoking.
