what feature of the epithelial lining of the respiratory tract is responsible for the smokers cough?
because of lung surfactrant
When tobacco smoke is inhaled into the respiratory system, the cilia begin to beat slowly. With time, the cilia, which act like a filter, disintegrate and eventually die away. This leads to smokers getting what is known as a smoker's cough.
there are at least 400 fires started by careless smokers each year.
the anti smoke law was made to protect non smokers and also to try to help smokers to quit smoking!

passive smokers
Yes. e.g not all asthmatics are smokers.
Respiratory infections
because of lung surfactrant
yes
In most opinions, no..Smokers are aware of the danger.
it is a group of respiratory symptoms seen in smokers; includes coughing wheezing, vocal hoarseness, pharyngitis, dyspenia, and susceptibility to respiratory infections.
Emphysema is not contagious, and someone with emphysema can be around a child with respiratory problems without endangering the child. Smokers should not be around a child with respiratory problems.
Epithelial cells in the respiratory tract protect the aveoli from infection by secreting mucus that traps bacteria and other particles. Micro villi push the mucus back up towards the digestive system in something called a "mucus escalator". In chronic smokers these epithelial cells actually change type, removing the mucus escalator function. This loss of function is the pathophysiology behind smokers cough, as they must cough up the mucus they produce.
If a smoker is trying to expel mucus in the respiratory passages, that is done by coughing. Smokers often cough.
Respiratory Illness
For example, children living with smokers are twice as likely to have respiratory problems as children living with nonsmokers.
