The Result of Cigarette Smoke Nobody Understands About

Everybody and their mom know that cigarette smoke is harmful. In reality, it's the leading cause of preventable death in the United States. There are 480,000 deaths a year that occur from cancer, respiratory disease, vascular disease and various other kinds of problems as an outcome of cigarette smoke (Tobacco-Related Mortality). The killers in cigarette smoke originated from the variety of risky chemicals - from tar to carbon monoxide gas - that are all rolled into a single cigarette (What's in a Cigarette?). It's this mixture of chemicals that when lit, makes cigarette smoke so profoundly damaging to our bodies.

These unsettling truths about cigarette smoke are well-known by everybody, however what most of people do not understand is the direct impact that cigarette smoke has on the cells of the respiratory system. That is, it actually changes the shape and structure of the cell. It's not the favorable type of change like when a worked out muscle goes through hypertrophy and increases mass, but more like turning a square cell into a flat egg-shaped cell.

When cigarette smoke is inhaled it cruises along the respiratory tract till it reaches the lungs, and then gets exhaled out. Inside your respiratory tract is a variety of cells which when hit with cigarette smoke repeatedly gradually, can undergo - in this case - a nasty process called metaplasia.

Metaplasia is a procedure in the body that changes a particular kind of cell into another better type. This ultimately changes the structure and function of the cell. It can happen naturally and as a positive procedure, such as in cartilage developing into bone through ossification, or it can take place unusually with negative impacts through anxiety or toxic duplicated stimuli.


The metaplasia of the respiratory tract cells as you may think, is negative. The duplicated intake of cigarette smoke on the respiratory tract can alter the cells from a square-shaped cell - called columnar- with cilia (little hairs that help trap dust) to squamous shaped (which resembles a fried egg) without any cilia. Of getting a much better photo of exactly what the cells in the respiratory system can turn into, squamous shaped cells are exactly what comprise the outer part of the epidermis. To imagine the process of squamous metaplasia, picture a row of durable strong cinderblocks safeguarding the floor below it. Now picture gradually with repeated intake of unsafe compounds those cinderblocks become a stack of dough. Well, with the repeated direct exposure to cigarette smoke, that's what can occur inside the respiratory system.

Squamous metaplasia from tobacco smoke affects several parts of the respiratory system including the cells in the throat and the bronchus. The damage does not just stop there either: squamous metaplasia is directly connected with chronic obstructive lung illness - COPD - which is a very worrying subject these days.

Aside from the widely known effects from smoking cigarettes, like cancer, vascular illness, association with miscarriages, impotence, macular degeneration, etc., one of cigarettes most lethal adverse effects is chronic obstructive lung disease (COPD). COPD is a progressive condition that makes breathing tough and can cause exactly what's typically understood as 'smokers cough'. It is the 3rd leading cause of death in the United States and is straight related to smoking cigarettes tobacco items ("Chronic Obstructive Pulmonary Disease (COPD) Fact Sheet).

Oddly enough, squamous metaplasia is really one of the human body's lots of defense systems when it comes to harm from cigarette smoke. The human body is constantly trying to recover balance within itself and when it comes to harm from tobacco smoke, changing the shape and function of its cells is a necessity to keep the obstacle in the respiratory system still helpful (Bolton).

It is accepted all over that cigarettes have a destructive effect on the human body. Though that reality is known, not everybody understands a few of the exact effects cigarette smoke has. Squamous metaplasia is one of those effects. Through altering the shape and function of the cell, squamous metaplasia silently affects the cells of the respiratory system. So closely connected with COPD, squamous metaplasia is not only a nasty outcome of cigarette smoke however a fatal one also.

There are 480,000 deaths a year that take place from cancer, respiratory condition, vascular disease and various other types of problems as a result of cigarette smoke (Tobacco-Related Mortality). The killers in cigarette smoke come from the range of perilous chemicals - from tar to carbon monoxide - that are all rolled into a single cigarette (What's in a Cigarette?). These unsettling realities about cigarette smoke are widely known by everybody, but what the majority of people do not understand is the direct effect that cigarette smoke has on the cells of the respiratory system. The duplicated consumption of cigarette smoke on the respiratory system can alter the cells from a square-shaped cell - called columnar- with cilia (little hairs that assist trap dust) to squamous shaped (which looks like a fried egg) without any cilia. Well, with the repeated direct exposure to cigarette smoke, that's exactly what can take place inside the respiratory system.
