  • Effects on the body
    • Carbon monoxide
      • Binds to the  haemoglobin to form carboxyhaemoglobin
        • Haemoglobin has a greater affinity for carbon monoxide; less effective oxygenation of haemoglobin
        • Can result in shortness of breath + increased heart rate
      • Also damage lining of the arteries
        • Haemoglobin has a greater affinity for carbon monoxide; less effective oxygenation of haemoglobin
    • Nicotine
      • Addictive !!!
      • Causes the release of hormone adrenaline.- increases heart /breathing rate, causes constriction of the arterioles
        • This raises the blood pressure in arteries
      • Causes constriction of arterioles leading to the extremities of the body- results in a reduced blood flow to the extremities
      • Affects the platelets to make them sticky
