Chemicals in Tobacco

WHAT’S THAT PICTURE? Small Groups 9 Pictures 1 Minute for Every Picture Write down everything that comes to mind

ACETONE Definition: A strong smelling, clear liquid Example: Nail Polish Remover Some Health Concerns have been expressed about the effects of Acetone. For example, some sources suggest that exposure to moderate-to-high amounts of acetone can irritate the eyes and respiratory system, and make people feel dizzy.

AMMONIA Definition: a colorless gas with a characteristic strong smell. Example: cleaning supplies Tobacco companies discovered that adding ammonia to the cigarette manufacturing process helps convert bound nicotine molecules in tobacco smoke into free nicotine molecules. This process is known as “freebasing.” Similar to the chemical process of freebasing cocaine, the end result is an enhanced effect of the drug on the user.

BENZENE Definition: A colorless, flammable, toxic, liquid. Example: gasoline Benzene is known to cause cancer, based on evidence in both people and lab animals. The link between benzene and cancer has largely focused on leukemia and cancers of other blood cells.

CADMIUM Definition: toxic metal Example: batteries Nausea, vomiting Diarrhea Muscle cramps Salivation Sensory disturbances Liver injury Convulsions Shock Renal failure

CARBON MONOXIDE Definition: a colorless, odorless toxic flammable gas Example: Car Exhaust Symptoms of Carbon Monoxide exposure may mimic influenza and include fatigue, headache, dizziness, nausea and vomiting, mental confusion, and rapid heart rate. Depending on the level of Exposure, Carbon Monoxide can be immediately fatal.

FORMALDEHYDE Definition: gas used to preserve. Example: save dead bodies Lab studies have shown that exposure to formaldehyde could cause nasal cancer in rate, and some studies of industrial workers have suggested that formaldehyde exposure might be associated with nasal cancer and nasopharyngeal cancer in humans

LEAD Definition: naturally occurring metal. Example: old pencils or paint. Lead poisoning affects nearly every system in the body, and may occur without noticeable symptoms. Low but ongoing exposure over time can affect the developing nervous systems (children are most at risk) in subtle but persistent ways

MERCURY Definition: a heavy silvery-white, very poisonous metal Example: old thermometer. In adults, Mercury poisoning can adversely affect fertility and blood pressure regulation and can cause memory loss, tremors, vision loss, and numbness of the fingers and toes. A growing body of evidence suggests that exposure to mercury may also lead to heart disease.

TAR Definition: dark, thick, flammable liquid Example: road pavement. The idea was that the filter would trap harmful tars and nicotine, but the design never worked as well as hoped. Toxins still make it through and into the smoker’s lungs, exposing them to the risks of smoking-related disease.

ARE THE CHEMICALS REALLY THAT BAD?

The Respiratory System

TURN AND TALK How does your body pull air in and push air out? Where does air travel when it enters the body? How does air move into your blood?

How does the Respiratory System Work? The Respiratory System Video

Passage of Air to the Lungs Enters through the Nose/Mouth Goes through the Esophagus Passes the Epiglottis Enters the Trachea Breaks off into the Left and Right Bronchi (Enters Lungs) Enters Bronchioles Goes through Alveoli (Covered by Capillaries that exchange oxygen and carbon dioxide)

How Breathing Works Inhaling: Your diaphragm moves down and your ribcage moves up, creating more room in your chest. This causes air to flow into your body through the nose/mouth. The air then moves past the epiglottis and into the trachea and bronchi.

How Breathing Works Exhaling: Your diaphragm moves up and your ribs move down, pushing air out of your lungs. The air, now containing carbon dioxide, moves back through

Captain Oxygen Storyboard Using your PowerPoint notes, please complete the mission below. Healthy comics just hired you as a new comic strip writer and artist. For your first project, you’ve been assigned to write and illustrate a comic strip about Captain Oxygen’s journey through the Human respiratory system. All 9 blanks must be filled in and the bottom lines must be captions explaining which step in the journey Captain Oxygen is.
