1. Oral cavity and throat: The heat generated by the burning of nicotine, a toxic substance in smoke, will stimulate the oral mucosa and gums and cause mucosal damage, leading to periodontitis, halitosis, oral leukoplakia and oral cancer (smokers are prone to tongue cancer and smokers are prone to lip cancer), which will damage the throat mucosa and cause chronic pharyngitis.
Second, trachea and bronchus: there is a layer of cilia on the surface of trachea and bronchus. If you smoke for a long time, tar will stick to the surface of this cilia and affect your swing. After the cilia swing is not smooth, the function of removing harmful substances and foreign bodies will be weakened, which will increase the incidence of chronic bronchitis and chronic obstructive pulmonary disease.
Third, the lungs: tar, carbon monoxide, nicotine and other harmful substances reach the lungs, similar to gas poisoning. After carbon monoxide enters the blood, it will quickly "plunder" and "rely on" the advantage of being several times stronger than oxygen, and squeeze out oxygen to "forcibly" combine with hemoglobin, resulting in insufficient oxygen supply in blood circulation throughout the body.
4. Blood: After the chemicals in tobacco enter the blood circulation, they are filtered by the kidneys and then discharged from the urine through the bladder. They can destroy cells in the bladder, thus increasing the risk of cancer.
5. Brain: When smoking, harmful substances can reach the brain within 7~ 10 seconds, causing brain excitement.
Six, the heart: hypoxia has caused a burden on the heart, and the heart has to work hard. Nicotine and carbon monoxide in tobacco can damage the intima of coronary artery, thus forming coronary heart disease; It will also cause abnormal vascular environment, increased platelet aggregation and increased blood viscosity, which is easy to form thrombosis. In addition, nicotine can also cause abnormalities in the cardiac conduction system.
Stomach: Nicotine in tobacco can cause gastric ulcer, delay the healing of ulcer, and also destroy the normal activities of gastrointestinal tract, leading to the occurrence of gastric diseases.
Eight, kidney, brain: smoking can also increase adrenal gland secretion, which can promote platelet aggregation, which is also the reason for the increase of blood viscosity. The increase of blood viscosity makes the blood flow slow, in which red blood cells and platelets are easy to aggregate, blocking blood flow and causing ischemic cerebrovascular diseases.
9. Skin: Like sun exposure, smoke can also cause elastin and elastic fibers to thicken or break. The reduction of oxygen supply will also affect the formation of collagen, the main component of skin, leading to dryness of skin, thus aggravating the appearance of wrinkles.
There are differences between men and women:
Male: inhibit the secretion of sex hormones, kill sperm and hinder the combination of sperm and eggs. Greatly reduce sexual desire and women's chances of conception.
Female: menstrual disorders, abortion, early menopause and other symptoms. The symptoms of postmenopausal osteoporosis are more serious.
