  • high blood pressure and heart disease
  • smoking can increase blood pressure, carbon monoxide combines with haemoglobin in red blood cells which reduces the amount of O2 they can carry. to make up for this, heart rate has to increase. heart contracts faster, whivh increases blood pressure
    • high blood pressure and heart disease
  • nicotine also increase heart rate , the heart contracts more often increasing blood pressure

    • if your diet is high in saturated fats and or salts it can increase the risk of heart disease!
      • saturated fats can build up cholesterol, cholesterol's a fatty substance. you need some cholesterol for making things like cell membranes but to much can lead to a build up of cholesterol in your arteries
