The recurring intake of cigarette smoke on the respiratory tract can change the cells from a square-shaped mobile – called columnar- with cilia (tiny hairs that support trap dust) to squamous formed (which resembles a fried egg) without having any cilia. To get a better photo of what the cells in the respiratory tract can switch into, squamous shaped cells are what make up the outer part of the epidermis.

Now think about more than time with repeated intake of harmful substances people cinderblocks switch into a pile of dough. Well, with the recurring exposure to cigarette smoke, that’s what can take place within the respiratory technique.
