Effects of Smoking on Respiratory Health

A long-term lung disease characterized by inflammation of the airways.

Smoking reduces the efficiency of gas exchange in the lungs.

Nicotine in cigarettes causes a physiological dependence.

Smoking causes various health problems, affecting many organs, leading to diseases.

Smoking harms various organs, potentially leading to severe diseases.

Around 15% of deaths worldwide are linked to smoking. This highlights the serious global health impact.

Smokers have a life expectancy at least 10 years shorter than non-smokers. This emphasizes the long-term consequences of smoking.

Smoking increases the risk of stomach cancer, affecting digestion and causing complications.

Smoking significantly increases the risk of stroke, affecting your brain and blood flow.

E-cigarettes contain nicotine, flavorings, and potentially harmful chemicals. They are considered harmful to health and banned in Hong Kong.

Tar deposited in the lungs coats the air sacs, reducing the surface area available for gas exchange, making it less efficient.

Carbon monoxide in cigarette smoke binds to hemoglobin in red blood cells, reducing the blood's ability to carry oxygen.

A chronic lung disease where the walls of air sacs are damaged, becoming less elastic, making it harder to breathe.

Smoking leads to the destruction of air sac walls, reduced surface area for gas exchange, and inflammation in the airways.

Smoking reduces gas exchange efficiency by: 1) Tar coating air sacs, 2) Carbon monoxide binding to hemoglobin, 3) Damage to air sac walls, 4) Inflammation and mucus build-up.

Smoking damages the air sacs, reducing their surface area, making gas exchange less efficient, and causing difficulty breathing.

Smoking narrows the airways due to inflammation and mucus buildup, making breathing difficult.
