    Study Notes

    Impact of Smoking on Gas Exchange System

    • Nicotine reduces the elasticity of alveoli, leading to impaired gas exchange.
    • Cigarette smoke contains harmful substances, including tar, nicotine, and carbon monoxide.
    • Tar is a black sticky substance that clogs the lungs and increases vulnerability to infections.
    • Nicotine is highly addictive, acting on the brain and contributing to elevated heart rates and narrowed arteries.
    • Carbon monoxide is a poisonous gas that binds with red blood cells, hindering their ability to transport oxygen.

    Effects on Ciliated Cells

    • Smoking damages ciliated cells in the respiratory tract, preventing effective mucus clearance.
    • Irritation from smoking can lead to chronic bronchitis and persistent cough.
    • Breakdown of alveolar lining results in reduced gas exchange efficiency.
    • Long-term smoking can lead to chronic obstructive pulmonary disease (COPD).

    Short-term and Long-term Effects of Smoking

    • Short-term effects include bad breath, increased heart rate, and shortness of breath.
    • Long-term effects include dependence, lung disease, increased risk of heart disease, and various cancers.

    Composition of Cigarette Smoke

    • Cigarettes contain over 7,000 chemicals, many being harmful.
    • Notable toxic substances include lead, hydrogen cyanide, ammonia, and polonium-210.

    • E-cigarettes produce vapor instead of smoke and are often considered a less harmful alternative to traditional cigarettes.
    • Usage of e-cigarettes is prevalent among youth, with 30% of young people aged 12-17 reported using them.
    • The long-term safety of e-cigarettes remains unknown due to the lack of extensive research.
