Cilia are important in mechanical removal of the bacteria from the upper respiratory tract. These treat the deposited bacteria by beating movements outwards, so the bacteria cannot enter the lower respiratory tract. However, with smoking the ciliary function is compromised rendering the lower respiratory tract vulnerable to the deposited bacteria resulting in increased infections. Carcinogens mostly influence very rapid division of already rapidly dividing cells in tissues. As a result rapidly dividing tissues in gastrointestinal tract, blood and bone marrow, respiratory tract, and integumentary system are prone to have cancers. Whereas, less rapidly dividing cells in tissues like nerves are less likely to have malignant diseases. A loss of 50% of a person’s functional skin surface would lead to a gross exposure of the underlying tissues to the environment leading to excessive dehydration due to fluid loss from evaporation and exposure of the underlying tissues to the risk of infection due to loss of barrier.
