  • 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

More effects to the body
More effects to the body

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.
