Answer:
Smoking and cardiovascular disease
Smoking increases the risk of cardiovascular disease in several ways:
Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.
Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.
The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.
Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.
