- Smoking
- Short term effects
- Tar
- Settles on the lining of the airways and alveoli.
- Increases diffusion distance in gas exchange.
- Combination of chemicals
- May cause an allergic reaction. smooth muscle contracts.
- Lumen of airway gets smaller, restricting air flow to alveoli.
- May cause an allergic reaction. smooth muscle contracts.
- Paralyses cilia and stimulates goblet cells.
- Pathogens trapped in mucus and not removed. Multiply.
- Block bronchioles
- More susceptible to infection.
- Pathogens trapped in mucus and not removed. Multiply.
- Settles on the lining of the airways and alveoli.
- Tar
- Problems to blood system
- Coronary Heart Disease
- Reduced blood flow to heart muscles
- Herat attack or myocardial infarction
- Angina
- Heart Failure
- Reduced blood flow to heart muscles
- Stroke
- Death of part of the brain tissue
- Loss of blood flow to that part of the brain
- Artery leading to brain bursts.
- Blood clot
- Loss of blood flow to that part of the brain
- Death of part of the brain tissue
- Thrombosis
- Blood flowing past plaque can't pass smoothly.
- Thrombus
- Sticky platelets
- Thrombus
- RBCs stick to fatty substances
- Blood flowing past plaque can't pass smoothly.
- Atherosclerosis
- Damage to inner lining of arteries
- Repaired by phagocytes
- Encourage growth of smooth muscle and deposition of fatty substances.
- Atheromas may grow enough to break through
- Forms a plaque
- Sticks out into lumen
- Forms a plaque
- Atheromas may grow enough to break through
- Encourage growth of smooth muscle and deposition of fatty substances.
- Repaired by phagocytes
- Damage to inner lining of arteries
- Coronary Heart Disease
- Diseases related to smoking
- Chronic Bronchitis
- Inflammation of lining of airways.
- Continual cough, coughing up mucus.
- Too much mucus
- Continual cough, coughing up mucus.
- Too much mucus
- Inflammation of lining of airways.
- Emphysema
- Loss of elasticity in alveoli.
- Alveoli burst
- Less SA for gas exchange
- Alveoli burst
- Shallow, rapid breathing
- Fatigue
- Loss of elasticity in alveoli.
- COPD
- Combination of diseases
- Emphysema
- Asthma
- Chronic Bronchitis
- Combination of diseases
- Lung Cancer
- Continual cough
- Shortness of breath
- Angina
- Coughing up blood
- Chronic Bronchitis
- Blood
- Nicotine
- Addiction
- Sensitive Nervous System
- Feels more alert
- Releases adrenaline
- increases heart rate and breathing rate. Constricts arterioles
- Raises blood pressure in arterioles
- Reduces blood and oxygen to extremeties
- increases heart rate and breathing rate. Constricts arterioles
- Makes platelets sticky
- Increases risk or blood clot or thrombus
- Carbon Monoxide
- Combines with haemoglobin
- Reduces oxygen carrying capacity of blood
- Raises heart rate
- Reduces oxygen carrying capacity of blood
- Damages the lining of the arteries
- Combines with haemoglobin
- Nicotine
- Long term effects
- Smokers cough resulting from irritation of airways.
- Damages delicate linings of airways and alveoli.
- Replaced by less flexible scar tissue.
- Reduces airway lumen, airflow is permanently restricted.
- Smooth muscle thickens.
- Reduces airway lumen, airflow is permanently restricted.
- Replaced by less flexible scar tissue.
- Damages delicate linings of airways and alveoli.
- Frequent infections inflame the lining of airways.
- Attract white blood cells.
- Release elastin to get to infection.
- No recoil. Bronchioles collapse. Alveoli burst.
- Release elastin to get to infection.
- Attract white blood cells.
- Lung Cancer
- Tar contains carcinogens.
- Smokers cough resulting from irritation of airways.
- Short term effects
