You breathe in and out anywhere from 15 to 25 times per minute,
Without even thinking about it.

How Smoking Hurts Your Lungs
Smoking damages your lungs natural cleaning and repair system and traps cancer-causing chemicals in your lungs.
Smoking destroys the tiny hairs (cilia), which line the upper airways and protect against infection. Normally, there is a thin layer of mucous and thousands of these cilia lining the insides of your breathing tubes.
The mucous traps the little bits of dirt and pollution you breathe in, and the cilia move together like a wave to push the dirt-filled mucous out of your lungs. Then you cough, swallow, or spit up the mucous, and the dirt is out of your lungs.
When your lungs’ natural cleaning and repair system is damaged, germs, dirt and chemicals from cigarette smoke stay inside your lungs. This puts you at risk for chronic cough, chest infections, lung cancer and COPD.
The patient is a 57 year old, with a 75 pack year history of smoking, who was found to have a carcinoma in the upper portion of his right lung.
