Cigarette. A cigarette (/ˌsɪɡəˈrɛt/; from the French word cigarette [siɡaʁɛt], meaning "small cigar")[1] is a small cylinder of finely cut tobacco leaves rolled in thin paper for smoking. The cigarette is ignited at one end and allowed to smoulder; its smoke is inhaled from the other end, which is held in or to the mouth; in some cases a cigarette holder may be used as well. Most modern manufactured cigarettes are filtered and include reconstituted tobacco and other additives.[2] Rates of cigarette smoking vary widely, and have changed considerably over the course of history — since cigarettes were first widely used in the mid-20th century. While rates of smoking have over time leveled off or declined in the developed world, they continue to rise in developing nations.[3][4] Cigarettes carry serious health risks, which are more prevalent than in other tobacco products.

The Effects Of Cigarette Smoking On The Respiratory System. 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. 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.
