Smoking affects breathing system, facts and diseases.
Smoking affects breathing system, facts and diseases.
The major health problems caused by smoking affect the nicotine delivery system: the airways, blood vessels and lungs in the human respiratory system. During normal breathing, air is ingested through the nose or mouth and travels through the bronchial tubes to the lungs. There, the oxygen collects in the alveoli, or air sacs, and diffuses into the bloodstream, to be pumped by the heart to the brain and body. Cigarette smoking upsets this balanced process, to the detriment of the respiratory system.
Effects on the Mouth, Larynx and Pharynx Hot gases and particulate, inhaled during cigarette smoking, contact the tissue and mucous membranes that surround the mouth; larynx, or voice box, and pharynx, or throat. These areas suffer continual irritation from smoking, and tobacco users may develop symptoms such as hoarseness, coughing and wheezing due to inflammation.
As the National Institutes of Health report, cigarette smoke contains more than 60 cancer-causing compounds. The U.S. Surgeon General has linked mouth, larynx and pharynx cancers with tobacco use.
Effects on the Bronchi Chemicals and particulate from tobacco use continue on to the bronchi, the airways that lead to the lungs. There, the smoke acts on the cilia, tiny hairs that sweep away debris to keep the airways clear. When damaged cilia can no longer function, excess mucus and foreign matter clog the bronchial space.
The American Lung Association (ALA) relates that symptoms of chronic bronchitis arise to compensate for this health problem. A frequent cough and expulsion of phlegm indicate this first stage of chronic obstructive pulmonary disease (COPD).
Effects on the Lungs The alveoli of the lungs suffer from cigarette smoking, eventually breaking down and losing their effectiveness in transferring oxygen to the blood. This second stage of COPD, emphysema, is characterized by shortness of breath and difficulty exhaling, the ALA notes. COPD
