    • A stimulant increases the action of the CNS, heart and other organs

  • 4. Tar
    • Flavor is due to the tar in tobacco
    • Tar is thick, sticky, dark fluid produced when tobacco burns
    • It penetrates the airways and lungs
    • It combines with the drying effect of the smoke to paralyze or destroy the cilia
    • Contains several substances known as carcinogens
  • 5. Carbon Monoxide
    • A colorless, odorless, poisonous gas in smoke that passes through the lungs into the blood
    • Same as automobile exhaust fumes

  • 12. Chronic bronchitis
    • bronchi are irritated. As tar builds up, cilia become useless resulting in chronic coughing and excessive mucus secretion
  • 13. Emphysema
    • Involves destruction of the tiny air sacs in lungs
    • As walls are destroyed, they lose their elasticity and provide less total surface area for oxygen to be absorbed
    • Instead of using 5% of total energy to breathe, now using 80%
