When someone quits smoking, several respiratory system changes occur:
1. Cilia regain normal function: The tiny hair-like structures called cilia, which line the respiratory tract, start to regain their normal function. When smoking is stopped, the cilia that were previously paralyzed by the toxic chemicals in cigarettes can begin to recover and move in a coordinated manner. Restored ciliary function helps to clear mucus and trapped particles from the lungs, reducing the risk of respiratory infections.
2. Tar in the air passages dissolves: The tar present in the air passages gradually begins to dissolve. Tar is a sticky substance that is produced by burning tobacco, and it can accumulate in the lungs over time. When smoking is ceased, the body's natural defense mechanisms can work to break down and flush out the trapped tar. This process takes time and may vary from person to person.
It is important to note that while these changes occur, the damage caused by smoking to the respiratory system may not be entirely reversible. It is always recommended to quit smoking as early as possible to minimize the long-term health risks associated with smoking.
