The main ingredient in cigarettes is tobacco. Tobacco-green, dense, and grows in tropical climates. Many farmers use chemicals to tobacco plants. They use fertilizer to make the soil fertile and to kill insects that eat the tobacco plant.
Once selected tobacco plants dry, then the tobacco is cut into small pieces. Then, artificial flavorings and other chemicals are added. Several chemicals are put into cigarettes to smoke when cigarettes are not burnt out the fire but only just out embers.

There are more than 4,000 chemicals in cigarettes, including 51 substances known to trigger cancer. Cancer is a disease that most often kill people. There are many types of cancers: breast, lung, throat, stomach, kidney, leukemia (blood cancer), and other, cancer cells will divide and to form new cells that are abnormal or unhealthy.
Our bodies are made up of thousands of cells. In a healthy person, new cells are formed only when needed. In people who develop cancer, cells grow abnormally which will damage normal cells, if cells form new cells that are not needed, the cells will form an abnormal growth, these cells may initially small size as large as nuts or oranges, growth of the cancer called malignant tumors.
Cancer usually kill people when spread to other parts of the body. Sometimes cancer cells break away from a malignant tumor and found a way to get into the blood. Tumor spread to parts of the body or organs such as kidneys or lungs. Then the tumor began to spread and multiply his cell and a new form of cancer. For example, if a woman who has a malignant tumor in breast cancer and not menyembukan when young cancer age, sections of the tumor and may spread into the blood. From the blood may be spread to the brain and cause brain cancer patients.
Chemicals in cigarettes and cigarette smoke is known not only cause cancer but also health problems serious. Many of the chemicals are toxic if someone sucking a pack of cigarettes, cigarette exploiters will die.
The three poisons are the most widely known chemical nicotine, tar, and carbon monoxide. Nicotine contained in the main ingredient in the insecticide in pure form, with only one drop in the human tongue will cause death.
Tar is an oily substance. When a smoker smoking cigarettes, the amount of tar that many will stick to the lungs.
Carbon monoxide is a poisonous gas. Smokers suck just the same as the gas found in automobile exhaust. This gas mixes with respiratory and circulatory system (heart, arteries, and veins). When we inhale air through your nose and mouth, air passes through the tube and bronchus into the lungs. Fine hairs are small and mucus (sticky fluid is also found in the nose) which helps to clean the air will move into and the lungs.
Humans have two lungs are protected by the rib cage and separated by the heart. Lungs someone who does not smoke (healthy), the lungs are soft, rubbery, gray-colored tissue reddish.
The lungs also have hundreds of air bags that contain oxygen when we breathe the air or the bernafas.Paru-lung elastic like rubber.
One of the tasks of the lungs to take oxygen from the air and oxygen in the blood will flow to the heart. The heart pumps blood that contains oxygen to the body by the arteries. The lungs also have to remove the carbon dioxide which is a waste product from the cells by way of breath
When smoking, the carbon monoxide in the smoke will enter into the bloodstream. Does This will reduce the amount of oxygen available to the heart. In addition, chemicals in cigarette smoke narrows the walls of the arteries. With a lack of oxygen that passes through the arteries, the heart must work harder. Blood pressure will also increase.
Consequently the heart does not receive enough oxygen in the blood. When this happens, the heart will stop beating and some or all of the heart muscle will die. This is called coronary heart attack. If most part of the heart muscle stops working, people will die.
