Lungs Those who smokes a lot of sick lung cancer is twenty times more likely than non-smokers. Therefore, we can safely say that lung cancer develops primarily motivated by smoking. Cancer is often so easy launches, it's impossible to save the patient even at the cost of removal of the entire lung.
In medical science, there are many works that show the harm of smoking. Scientists took 200-300 thousand people close to each other by age, employment, domestic conditions. The difference only, smoke or not. It turns: lung cancer among non-smokers occurs 12 times in the hundred thousands. Among those who tooth cigarette pack a day - 112, and of those two-tooth tutus - 284.
It also proved that the tobacco tar imposed by the experimental animals in the lungs or the skin, causes cancer in all cases.
Cardiovascular system
Smoking causes premature wear of the heart, vessels, as well as other vital organs.
One cigarette cigarettes increases the pulse of the twenty-strokes per minute, raising pressure on the few tens of millimeters, reduces cutaneous temperature. These changes stick around thirty minutes.
Thus, during the day, the heart is constantly receiving extra load, which, over time, leads to the disease.
When inhaled tobacco smoke vessels narrowed, and talk of blood on them slowed down and in some cases even at some point suspended. Slowing currents in the blood vessels of heart coronary insufficiency manifest, that is more an attack on the heart. Therefore, smoking, as a rule, increases or raises attacks coronary insufficiency. For many patients, these attacks immediately disappear as soon as they cease to smoke.
The World Health Organization, examining the role of tobacco, found that smokers die of coronary thrombosis at four years earlier than non-smokers.
People with vascular disease smoking causes a sharp spasm, causing any treatment will be futile, if the patient continues to smoke.
For such patients even stay in the atmosphere of tobacco smoke can be devastating. The experience with such patients have shown that delaying even unlit cigarettes led to a marked reduction in blood currents finger. Sometimes these patients all the time, there was a complete cessation of smoking current of blood in podnogtevom bed. The temperature of hands and feet fingers declined to six degrees.
Interestingly, the use of any filter cigarettes not warned in a current of blood and reduce fever.
The impact of tobacco on the heart said, for example, such an experiment: an isolated rabbit heart rhythmically works because through blood vessels, the heart of power, constantly runs a special physiological solution, approaching there are signs of blood. But if you take the smoke, to shake out of it all remaining tobacco, and on tissue paper onto this solution with a piece of paper and put in a drop of this system snabzhayuschuyu heart saline solution, the heart stops.
The dramatic impact of tobacco on the human heart to some extent mitigated by compensatory mechanisms that mobilize the body to fight the harmful chemical. Nevertheless, his influence remains, and gradually leads to premature decrepitude, disability and old age early approximation.
Brain and nervous system
About Harmful effects of nicotine on the central nervous system can be judged on the Effects of the first vykurennoy smoke: nausea, vomiting, cold sweats, sometimes loss of consciousness - these are symptoms that are talking about poisoning brain cells.
Gastrointestinal system
Smoker sometimes say: smoking makes food more delicious. Of course, if pre-filled mouth of any bitterness, then after that most normal foods seem delicious. In fact, smoking reduces appetite. It has long been observed: drop-outs in the smoke starts to add weight. After the cessation of nicotine intoxication all metabolic processes are improving, it is better digested food consumed.
A fatal outcome
In tobacco contains nicotine - extremely poisonous substance. Vykuriv cigarette pack, the man absorbs lethal dose of it. No tutus vykurivaetsya not immediately - a person produces a certain resistance to poison.
Statistics said: mortality from cardiovascular disease among many smokers twice higher than among non-smokers.
According to the World Health Organization, smokers die from pneumonia tenfold, from stomach ulcers to six times more likely than non-smokers.
