What are the body systems that smoking cigarettes can affect? What are the long and/or short term effects on that particular system?

Today’s Objectives: Describe how tobacco use affects the body systems

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.

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.

Short-term Effects Shortness of breath Reduced energy Coughing and coughing up phlegm (mucus). Cold and flus are more frequent Long-term effects Risk of lung cancer & emphysema

Short-term Effects Upset stomach Dulled taste buds Tooth decay Long-term Effects Risk of cancer of bladder, mouth, and throat Gum and tooth disease Stomach ulcers
