Odorless, colorless gas Replaces the oxygen in red blood cells Shortness of breath Causes a build-up of cholesterol in the arteries Chemicals in smoke Acetones An easily evaporated fragrant flammable liquid compound used to dissolve or to make chemical compounds. Found in nail polish remover Acetic Acid A colorless strongsmelling liquid acid that gives the sour taste to vinegar and that is used especially in making chemical compounds (as plastics) Ammonia a colorless gas that is used to make fertilizers, and explosives. Arsenic A solid poisonous element that is commonly metallic steelgray and brittle. Butane Flammable gases that are used especially as a fuel. Used as a lighter fluid. Cadmium A bluish white metallic element. Used in rechargeable batteries. DDT A colorless, formerly used insecticide, that is poisonous to many animals with backbones. Ethanol A colorless flammable easily evaporated liquid that is used to dissolve things and that is found in alcoholic beverages. Formaldehyde A colorless gas that consists of carbon, hydrogen, and oxygen, has a sharp irritating odor, and when dissolved in water is used to disinfect or to prevent decay. Used as a preserver of body fluid. Hexamine Chemical also found in barbecue lighter fluid. Hydrogen Cyanide The chemical used to terminate life by means of the gas chamber. Methane A colorless odorless flammable gas that consists of carbon and hydrogen and is produced by decay of organic matter. Methanol A light flammable poisonous liquid alcohol that consists of carbon, hydrogen, and oxygen and is used especially as antifreeze and to dissolve things. Napthalene A hydrocarbon in the form of crystals usually obtained from coal tar and used in chemical manufacture and as a moth repellent. Nitrobenzene A colorless flammable liquid that evaporates easily and is used to make or dissolve other chemicals or as a motor fuel. Nitrous oxide phenols A white poisonous acidic compound present in tars from coal and wood that when dissolved to make a weak liquid mixture is used as a disinfectant. Stearic Acid Acid obtained by the breakdown of a hard fat. Example of hard fat: The solid fat of cattle and sheep used in soap, candles, and lubricants. Chemicals in Smoke Project There are many chemicals in cigarette smoke that are also found in other products. Find five examples of these products in magazines by using the “What’s in Cigarette Smoke?” worksheet as a reference. Cut the product out of the magazine to create a collage that represents a visual image of products that contain the same chemicals as cigarette smoke. Respiratory System Definitions Nose The preferred entrance for outside air into the respiratory system. Mouth Oral cavity in which air also enters the respiratory system, especially when nasal passage may be temporarily obstructed, as by a cold or during heavy exercise. Respiratory System Definitions Throat Windpipe Collects incoming air from the nose and mouth and passes it downward to the windpipe. The passage leading from the throat to the lungs. Voice box Contains vocal chords and creates sound by moving air. Respiratory System Definitions Alveoli Esophagus Very small air sacs that are the destination of air breathed in. The passage leading from the mouth and throat to the stomach. Ribs Bones supporting and protecting the chest cavity and they help the lungs expand and contract. Respiratory System Definitions Diaphragm The strong wall of muscle that separates the chest cavity from the abdominal cavity. By moving downward, it creates suction in the chest to draw in air and expand the lungs. Bronchial Tubes There are one for each lung, which subdivide into each lobe of the lungs. Respiratory System Definitions Bronchioles The smallest subdivisions of the bronchial tubes at the end of which are the alveoli. Epiglottis A flap of tissue that guards the entrance to the windpipe, closing when anything is swallowed that should go into the esophagus and stomach. Respiratory diagram answer key Nose 2. Mouth 3.

Why is second hand smoke so dangerous? Second hand smoke still contains the same chemicals.
