Four, smoking on lung damage

Smoking can cause bronchial epithelium cilia shorter and irregular and disorder and movement , reduce the local resistance, susceptible to infection. Smoking can cause lung cancer. 90% of the total mortality caused by smoking. Initial symptoms can not be detected, until the cancer cells spread to the blood vessels and other organs. Smoking also causes emphysema, lung bronchial accumulation of toxic substances, will

prevent the air inhaled and exhaled normally, cause lung cell expansion or burst, resulting in the sick difficulty breathing.

Five, smoking damage to the stomach

Persons suffering from gastrointestinal diseases, smoking enough for gastroenterology deteriorate. Suffering from gastric ulcer or duodenal ulcer, ulcer healing will slow

down, and even evolve into chronic disease. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, gastrointestinal tension often, resulting in loss of appetite smokers. In addition, nicotine causes vasoconstriction of the gastrointestinal mucosa, and the appetite.

Harm six, smoking on the whole skeleton

body. Smoking can cause pelvic inflammation and pain, severe back pain part of the National People's Congress has great smokers, this is because smoking can cause reduced blood flow to auricular disc, auricular disc and thus an early

2. Harmful ingredients , and harm of tobacco smoke.

Process smokers inhaled cigarette, the cigarette in incomplete combustion process and thermal chemical reaction synthesis of a series of thermal decomposition, the formation of a large number of new material, its chemical composition is very complex, the separation of harmful components of more than 3000 species from the smoke, the main toxic substances as nicotine (nicotine, tobacco tar,) carbon monoxide, hydrogen

cyanide, ammonia and aromatic compounds and other toxic substances.

1) nicotine. Nicotine is a smell, taste bitter, colorless transparent oily liquid, volatile strong, easily oxidized into dark gray in the air, can be quickly dissolved in water

and alcohol, through the mouth, nose, bronchial mucosa easily absorbed by the

body. Viscosity is absorbed into the body in nicotine can the skin surface, is a drug

that can make people addicted to. A cigarette contains nicotine can kill amuse, 20 nicotine in cigarettes can kill a cow. Human lethal dose is 50-70 mg ,equivalent to

the content of 20-25 in cigarette nicotine. There are two typical examples can illustrate this problem: healthy 40 year old British man a long-term smoking, engaged in a very important work, night smoke 14 cigars and 40 cigarettes, morning feel uncomfortable, the doctor rescue is invalid die. Another example is: France held a smoking contest winner in a club, he smoked 60 cigarettes, the future and the podium is dead, the other competitors in the competition for the dying, to the hospital.

So, why the daily cigarette smoking box (20) many more people, including

nicotine content greatly surpass the lethal dose, but acute poisoning deaths rarely? The reason is part of the nicotine in tobacco smoke is toxic formaldehyde in and out, but most are not continuous smoking, the nicotine is discontinuous slowly into the human body. In addition, cigarettes lit 50% nicotine with smoke diffusion into the air, 5% with cigarette butts thrown away, 25% were burning damage, only 20% is absorbed by the human body. And nicotine in vivo was soon detoxifications are excreted in the urine. Coupled with the long-term smokers, the body produces certain tolerance to nicotine, therefore the occurrence of acute poisoning phenomenon less harm, which makes many

people ignore and continue to smoke cigarettes.

2) tar. Is composed of several kinds of material mixed into, in the lungs will be concentrated into a viscous, carcinogenic substances. -- that is to say, it can

cause cancer, in which contact with the organization therefore, smokers of any part of the

respiratory tract (including oral and throat) has the possibility of cancer

occurrence. Smoking 15 to 20 cigarettes a day, it is easy to suffer from lung cancer, oral cancer or laryngeal cancer risk of death, 14 times larger than people not to

smoke. Usually, the respiratory tract can swing a nap on the lung, continuous particles and bacteria swept into the formation of phlegm mucus and their discharge, and of the chemicals in tobacco smoke in addition to cancer, but also the gradual destruction

of the respiratory tract of the vile, increased mucus secretion, bacteria long time remained in the lung, the lung the occurrence of chronic disease, susceptible to bronchitis. Smokers cough is due to the mechanical performance of clean lungs had been damaged, and the sputum volume increased. In addition, the cell membrane tar will directly damage the alveolar epithelial cells, and destroy the cell membrane permeability, will eventually lead to emphysema. This is the main reason for smoking can lead to chronic bronchitis and emphysema.

3) carbon monoxide . Very easy with the red cell hemoglobin binding, causes red blood cells to reduce the oxygen carrying capacity, thus increasing the burden on the

heart, causing heart attacks, a serious cause of death.

Smoking is harmful to the human health by following a set of data may be better able to explain the problem:

85% of all lung cancer cases are caused by smoking;

In oral cancer, 50%-70% associated with smoking;

In the kidney and bladder cancer associated with smoking, 30%-40%;

10% of sudden infant death caused by passive smoking.
