A short animated explainer on what smoking and drinking do to the body. The narration describes nicotine stimulating adrenaline release, carbon monoxide displacing oxygen in the blood, fatty deposits narrowing arteries, and alcohol affecting the heart muscle, liver, stomach lining and kidneys.
Key points
- Smoking is shown stimulating adrenaline release and raising heart rate and blood pressure
- Carbon monoxide from smoke is described as taking the place of oxygen in blood
- Fatty deposits are shown narrowing the arteries and increasing the heart workload
- Alcohol is described as disturbing heart rhythm and weakening heart muscle contraction
- Effects on the liver, stomach lining and kidney water loss are also described
Video Transcript
A short animated explainer on what smoking and drinking do to the body. The narration lists the effects in sequence: nicotine stimulating adrenaline release and raising heart rate and blood pressure, carbon monoxide taking the place of oxygen in the blood, atheroma narrowing the arteries, and alcohol's effects on the heart muscle, the liver, the stomach lining and the kidneys.

Smoking and drinking cause stressful changes to the body and its organs and tissues. When smoking, the brain is stimulated and sends signals to the adrenal glands to release norepinephrine, which raises the heart rate. Carbon monoxide enters the blood in place of oxygen. The nicotine present in the smoke of the cigarette raises the body's blood pressure. Atheroma builds up and blocks the arteries, which if totally blocked increases the heart's workload, sometimes with fatal consequences. The consumption of alcohol causes intoxication. Alcohol makes the heart beat abnormally and decreases the force of heart muscle contraction.
Seroces of the liver is caused by excess alcohol, and alcohol also inflames the stomach lining. Increased water loss from the kidney leading to dehydration is also an effect of alcohol.
