1. Unit 5: Tobacco

2. Lesson 1: What Tobacco Does to Your Body
The Facts About Tobacco
A single puff of tobacco smoke exposes the body to more than 4,000 chemicals Almost all of these make the body unable to work as it should. At least 43 of the chemicals in tobacco smoke are known to cause cancer in smokers.

3. What is in tobacco?
Three substances in tobacco smoke are especially harmful to your health.
Nicotine is an addictive drug found in tobacco. This drug makes tobacco users crave more nicotine.
Tar is a thick, dark liquid that forms when tobacco burns. This liquid covers the lining of the lungs, causing disease.
Carbon monoxide is a colorless, odorless, poisonous gas produced when tobacco burns.

4. Two forms of tobacco are placed in the mouth instead of being smoked.
Tobacco in Many Forms
Cigarettes are made from shredded tobacco leaves. Although filters can reduce the amount of nicotine and tar in cigarette smoke, they do not help to decrease the amount of monoxide and other disease-causing chemicals.
Smokeless Tobacco
Two forms of tobacco are placed in the mouth instead of being smoked.
Chewing tobacco is made from compressed, coarsely ground leaves. A wad is placed between the cheek and gum, where it is sucked or chewed.
Snuff is a finely ground, powdery substance. It is placed between the lower lip and gum, where it mixes with saliva and is absorbed.
Smokeless tobacco is not a safe alternative to smoking tobacco. The nicotine in smokeless tobacco is just as harmful and addictive as that in cigarette smoke. In addition, smokeless tobacco is linked to an increased incidence of mouth cancer and cancers of the esophagus, larynx, and pancreas.

7. The Costs to Society
Smokers pay a high price for their tobacco habit, including the price of tobacco products and the cost of health care. Nonsmokers who are exposed to the tobacco smoke of others also pay a price. They are at increased risk for lung cancer and other respiratory diseases. The developing babies of pregnant women who smoke can also suffer serious effects. To help reduce all these costs to society, the government has regulated the tobacco industry. In 1964 health warnings began to appear on cigarette packs. In 1971 cigarette advertisements were banned from radio and television. New regulations, approved in 1996, limit access to persons under 18.

9. Lesson 2: The Respiratory System
Oxygen
Take a deep breath. Now let the air out. These two motions, inhaling and exhaling, are the basic actions of your respiratory system, the set of organs that supply your body with oxygen and rid your body of carbon dioxide. This process is crucial because you can only survive a few minutes without oxygen.

10. Parts of the Respiratory System
Many body parts work together to help you breathe. Air goes in and out through your nose and mouth. The lungs exchange oxygen and carbon dioxide. Muscles in your chest allow the lungs to expand.

12. Problems of the Respiratory System
The respiratory system is made up of many complex and delicate parts. Damage to the system may occur in several ways. For example, germs may enter through the nose and mouth. Tobacco smoking, inhaled chemicals, or environmental pollution may also cause damage.

15. Journal/Reflection Discuss the effects smoking has on the respiratory system (short term & long term) How did the straw activity simulate the effects of smoking over time? Was it hard for you to breathe? Did you feel shortness of breath/dizziness?
