Tobacco smoke is of two types one “side stream smoke” that is inhaled by the people around the smoker. This smoke is more dangerous because it is not filtered. The other type is “main stream smoke” which is inhaled by the person smoking the cigarette. This type of smoke is less toxic because the smoke passes through a filter, which reduces the amount of chemicals being inhaled.
Smoking makes the airways (the bronchioles) tighter and it makes it difficult to breath. The muscles of a smoker become stiff and breathing air work becomes difficult because the alveoli cannot strech as the have been damaged. if the muscles are damaged and donot have elasticity this can lead to asthma where the person has attacks and cannot breath properly. Once the elaticity of the lungs goes it never comes back it is a irreversible action, there is no way of repairing the damage. Smoking can make the lung tissues inflammed and swollen. As the lungs are swollen less oxygen is available to the blood that is why the smoker hands and feet appear to be blue.
