- Cresols, which is harmful to the human body acids. They irritate the mucous of the respiratory tract. Their inhalation causes intolerable cough;
- carbon dioxide (carbon dioxide) is a gaseous substance, having no color and smell. Frequent Smoking is dangerous prolonged suffocation;
- hydrogen cyanide is a substance, causing shortness of breath, influence the rhythm of breathing. If a strong poisoning, disturbed respiratory function;
- isoprene is a hydrocarbon. It is a volatile liquid, not having color. A pronounced odor. Otraslyam action exposed mucosa of the lower respiratory tract. Decay of isoprene is carried out in the lungs, what causes cancer;
- acetaldehyde is the basis of cigarette smoke. Causing smokers have a physical dependence;
- acrolein is a volatile liquid, having a pungent odor. When injected into the body causes the inflammation of the larynx and respiratory system. Able to mutate.
Tobacco smoke contains many elements of the periodic table, dangerous to health. The impact of electronic cigarettes on the lungs is also actively studied. You can say for sure, the components of this product also negatively affect the respiratory system.
Morphological changes in the lungs
Fascination cigarettes leads to structural changes of the lower respiratory. The most unpleasant thing, they are irreversible. It threatens the formation of inflammatory processes.
Lungs after Smoking filled with harmful smoke. If a person regularly consumes a pack of cigarettes, the respiratory system may fail. Almost 90 % smokers have lung problems. Poisonous substances cause:
- spasm;
- narrowing of the bronchi;
- deformation of the alveoli;
- the decrease in the function of ciliated epithelium;
- loss of elasticity of lung tissue and its deformation;
- inflammation of the lung or whole body;
- morphological changes of the lungs, they expand, the formation of holes, which is filled with air;
- reducing the size of on, swelling of the epithelium and the decay of the lung tissue, and replacing it with connective tissue.
Tobacco smoke is dangerous to their damaging effect on the vascular structure of organs. Is the thickening and hardening of the walls of arterioles, since the vascular endothelium is significantly growing. Impaired elasticity of the body.

If the experience of a smoker's significant, the cough becomes constant, painful with phlegm (when it becomes purulent complications). Aggravation of cough observed with the onset of cold weather.
The development of hypoxia
Smoking causes narrowing of lung tissue. It is a violation of the functions of gas exchange and ventilation, hypoxia. Affects all organs and primarily the lungs. Lung cancer from Smoking is the final diagnosis, who hears every tenth smoker more 20 years.
Hypoxia is dangerous for the following reasons:
- it affects the brain;
- the nervous system suffers;
- disturbed mental activity;
- there is a risk of suffocation and coma;
- lost protective functions of the body;
- inflammatory processes become chronic.
If a significant portion of affected lung tissue, it is the increase in temperature to 37,5⁰ (night). The patient marks the chills, there is pain in the chest area. Lungs after years of Smoking begin to accumulate harmful components, contained in cigarettes.
Problems with blood circulation
The penetration of poisons into the lower respiratory system are able to disrupt the function of blood circulation. Pulmonary hypertension develops rapidly. As a result, people suffering from various ailments:

- chronic bronchitis;
- pulmonary fibrosis;
- asthma;
- obstruction light;
