- Smoking- Nicotine and Carbon Monoxide
- Nicotine
- Chemical in cigarettes that causes addiction
- Has a variety of effects on the body
- The body becomes used to these effects and the smoker no longer feels well unless they have nicotine in their blood
- Mimics the action of transmitter substances at the synapses between the nerves.
- Makes nervous system more sensitive and the smoker feels more alert
- Causes the release of adrenaline.
- Has a variety of effects that prepares the body for activity
- Include increasing heart and breathing rate, and causing constriction of the arterioles
- Raises blood pressure in the arterioles
- Has a variety of effects that prepares the body for activity
- Include increasing heart and breathing rate, and causing constriction of the arterioles
- Raises blood pressure in the arterioles
- Raises blood pressure in the arterioles

- Has a variety of effects that prepares the body for activity
- Raises blood pressure in the arterioles
- Include increasing heart and breathing rate, and causing constriction of the arterioles
- Has a variety of effects that prepares the body for activity
- Causes constriction of the arterioles leading to the extremities of the body
- Reduces blood flow and oxygen delivery to the extremities
- In extreme cases cane lead to need for amputation
- Reduces blood flow and oxygen delivery to the extremities
- Also affects the platelets to make them sticky
- Increases the risk that a blood clot or thrombus may form
- Carbon Monoxide
- Enters red blood cells and combines with haemoglobin
- Combines much more readily than oxygen
- Forms stable compound carboxyhaemoglobin
- Reduces oxygen-carrying capacity of the blood
- Smokers will feel this when they exercise
- The body will detect the lower level of oxygen and it may cause heart rate to rise
- Smokers will feel this when they exercise
- Combines much more readily than oxygen
- Damages lining of the arteries
- Enters red blood cells and combines with haemoglobin
- Nicotine and Carbon Monoxide
- Enter the lings, and pass through the lung surface into the blood
- In blood they cause changes to circulation
- Changes lead to increased risk of cardiovascular diseases
- Atherosclerosis
- Coronary heart disease (CHD)
- Stroke
