Lesson 2

  • Today’s Objectives:

    • Describe how tobacco use affects the body systems


Journal entry

Journal Entry

  • What are the body systems that smoking cigarettes can affect?

  • What are the long and/or short term effects on that particular system?


Nervous system

Nervous System

  • Short-term effects

    • Changes take place in brain chemistry

      • Withdrawal symptoms

      • Heart Rate and BP increase

  • Long-term Effects

    • Increase risk of stroke due to decreased flow of Oxygen to the brain.


Circulatory system

Circulatory System

  • Short-Term Effects

    • Heart Rate increases

    • Energy reduced because less oxygen gets to the body tissues.

  • Long-term effects

    • Blood vessels are weakened and narrowed.

    • Cholesterol levels increase.

    • Blood vessels are clogged due to fatty buildup.

    • Oxygen flow to the heart is reduced

    • Risk of heart disease and stroke becomes greater.


Respiratory system

Respiratory System

  • Short-term Effects

    • Shortness of breath

    • Reduced energy

    • Coughing and coughing up phlegm (mucus).

    • Cold and flu are more frequent

  • Long-term effects

    • Risk of lung cancer & emphysema


Digestive system

    • Dulled taste buds

    • Tooth decay

  • Long-term Effects

    • Risk of cancer of bladder, mouth, and throat

    • Gum and tooth disease

    • Stomach ulcers


More effects to the body

More effects to the body

  • Chronic Obstructive Pulmonary Disease (COPD)

    • Condition in which passages in the lungs become swollen and irritated, eventually losing their elasticity.

    • Includes chronic bronchitis, asthma, and emphysema.

    • Causes over 100,000 deaths per year, 90% are linked to smoking.


More effects

More effects

  • Smokers are also at an increase risk of developing lung cancer.

  • Smoking is the leading cause of Cardiovascular Disease.

    • This is a disease of the heart and blood vessels.

Tobacco’s Addiction

  • Nicotine is the chemical that causes the addiction
