Whats the harm of smoking

Smoking does great harm to our health. A person who often smokes will affect the lungs and cause some diseases. So, what is the effect of smoking on the lungs? how long will the lungs blacken after smoking?
What diseases will smoking cause?
Smoking will cause chronic bronchitis, smoking will cause bronchial epithelial cells cilia short, irregular and its movement obstruction, reduce local resistance, easy to infection. The fine hairs of the lungs arranged on the airway, usually hydrogen foreign matter is removed from the lung tissue. These villi will continuously sweep lung particles into sputum and mucus, and the chemicals in the smoke will not only cause cancer, but also gradually destroy the villi and increase mucus secretion, causing chronic diseases in the lungs and prone to bronchitis.
Smoking can also cause emphysema, the accumulation of toxic substances in the bronchial trachea can prevent the normal exhalation of air inhaled by the human body penis pumping , lung cells expand or rupture, and patients have difficulty breathing. Due to the stimulation of smoke particles and harmful gases, the mononuclear giant food cell system in the respiratory tract is activated, and neutrophils gather and activate in the lungs, releasing a large number of toxic oxygen free radicals and various proteolytic enzymes. Acting on lung tissues such as elastin, polymucin, basement membrane and collagen fibers, the septum of the alveolar wall is destroyed and interstitial fibrosis.
Lung cancer is another serious disease caused by smoking. Among the causes of lung cancer in China, about 70% and 80% of men are smoking, while about 30% of women are smoking and passive smoking. In developed countries, 85% of lung cancer deaths are related to smoking. If smokers smoke an average of 20 cigarettes a day huge anal dildo , smokers who have smoked for 20 years have a 20 times higher risk of lung cancer than non-smokers. The number of lung cancer deaths among smokers under the age of 20 is 28 times higher than that of non-smokers. Passive smoking, often called secondhand smoke, is more dangerous than previously known, and women who live with smokers are six times more likely to develop lung cancer than ordinary people, according to a recent study by US medical researchers.
How long will the lungs blacken after smoking?
Take a pack of cigarettes a day as an example, the lungs usually turn black in 3 years gay dildo , but they also turn black in 1-2 years, depending on your physical fitness and smoking.
Tar and particles in tobacco enter the lungs and deposit in the lungs. Tobacco inhaled into the lungs is absorbed by alveoli and mucous membranes, and carbon residue and dust that have not been completely burned for a long time accumulate in the lungs. Long-term smoking blackens the lungs.
Harmful substances (acrolein, hydrocyanic acid, formaldehyde, etc.) contained in cigarettes inhibit the movement of ciliated cells on the inner surface of the bronchus, and even lead to ciliated cell necrosis. Ciliated cells can block the dust impurities in the air and purify the air. Once the ciliated cells are destroyed, the dust and impurities in the air will enter the lungs and deposit, aggravating the blackening of the lungs.
Cigarette lighting itself is a process of incomplete combustion, and the smoke generated is actually dusty air, which contains a certain amount of carbon monoxide and vaporized nicotine. Nicotine dependence, carbon monoxide is responsible for waking you up and harming your brain, and smoke tar is responsible for burning and generating smoke, that is, dust, even if your lungs turn black.
In addition to blackening the lungs magic wand vibrator , smoking can cause glands on the surface of the bronchi to proliferate, hormones that stimulate phlegm and cough, bronchioles to contract, and smoke that increases respiratory resistance that contains radioactive substances and heavy metals that can damage lung tissue.
