This text is a Descriptive text so the generic structure is:

How Does Smoking Effect Our Body? What is Smoking? Smoking is the inhalation of the smoke of burning tobacco encased cigarettes. Cigarettes is a dangerous product and addictive, because there are over 4.000 chemicals in cigarettes. 51 of them are known to be carcinogenic. A carcinogenic is something that causes cancer.

Chemical in cigarettes are known to cause not only cancer, but also other serious health problems that affect our body like lung and heart disease.(Identification)

When a cigarette is lit, all the chemicals in it react with one another in such a way that alters the way a healthy cell behaves. Healthy cells grow, make new cells and then die. Cells grow faster during childhood, but this process slows down by the time we reach adulthood. By then, most cells in the body are made only to take the place of the ones that die.

However, carcinogens affect a cell's DNA, causing damage that causes the cells to behave differently.

The damaged DNA in cancer cells is not fixed and causes cells to grow and make new cells in a way that is not orderly and healthy, but out of control. The damaged cells make new damaged and unhealthy cells that can spread throughout the body causing death and disease. According to the American Cancer Society, smoking kills at least 400,000 people every year. For those who smoking does not kill, it still creates a higher risk of disease for everything from heart disease to cancer. Our lungs take the largest hit when it comes to smoking.(description)1

When you smoke, you inhale large amounts of tar. This tar irritates the throat, as well as coats the cilia on your throat with a thick black mess. The cilia in your respiratory track and lungs are responsible for filtering out the toxins and allergens that you inhale everyday. Without them, you are left defenseless. Smoking also has an effect on your heart. When a person smokes cigarettes, the carbon monoxide (toxic gas) in the smoke gets into their blood stream. This reduces the amount of oxygen going to the heart.

In addition, the chemicals in cigarette smoke narrow the walls of the arteries. With less oxygen passing through the arteries, the heart must work harder. And then blood pressure also goes up. (description)2
