Describe how tobacco use affects the body systems

Lesson 2

Short-term effectsChanges take place in brain chemistry

Withdrawal symptomsHeart Rate and BP increase

Long-term EffectsIncrease risk of stroke due to decreased flow of

Oxygen to the brain.

Nervous System

Short-Term EffectsHeart Rate increasesEnergy reduced because less oxygen gets to the

body tissues.

Long-term effectsBlood vessels are weakened and narrowed.Cholesterol levels increase. Blood vessels are clogged due to fatty buildup. Oxygen flow to the heart is reducedRisk of heart disease and stroke becomes greater.

Circulatory System

Short-term EffectsShortness of breathReduced energyCoughing and coughing up phlegm (mucus).Cold and flus are more frequent

Long-term effectsRisk of lung cancer & emphysema

Respiratory System

Short-term EffectsUpset stomachDulled taste budsTooth decay

Long-term EffectsRisk of cancer of bladder, mouth, and throatGum and tooth diseaseStomach ulcers
