Answer:
Smoking and Respiratory Disease
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer.
Answer:
Inhaling tobacco smoke causes damage to many of the body's organs and system.
Explanation:
EFFECTS OF SMOKING ON THE RESPIRATORY SYSTEM:
•Irritation on the trachea (windpipe) and larynx (voice box)
•Reduce lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages.
•Impairment of the lungs' clearance system,leading to the build-up of poisonous substances,which result in lung irritation and damage
•Increased risk of lung infection and symptoms such as coughing and wheezing
•Permanent damage to the air sacs of the lungs
EFFECT OF SMOKING ON THE CIRCULATORY SYSTEM:
•Rate blood pressure and heart rate
•Constriction (tightening) of blood vessels in the skin,resulting in the drop in skin temperature
•Less oxygen carried by the blood during exercise
•'Stickier' blood,which is more prone to clotting
•Damage to the lining of the arteries,which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)
•Reduced blood flow to extremities (fingers and toes)
•Increased risk of stroke and heart attack due to blockages of the blood supply
