Question

How does smoking damage the lungs GCSE?.

Answer 1

Smoking harms the bronchioles and can eventually cause the loss of many lung alveoli.

The lining of arteries, notably the coronary arteries, is harmed by smoking. The injury promotes fatty material accumulation in the arteries. An attack on the heart or stroke may result from this. The amount of oxygen that the blood can carry is decreased by the inhalation of carbon monoxide found in cigarette smoke. Smoking cigarettes causes the heart to work harder because nicotine speeds up heart rate. It is possible for someone to get illnesses like emphysema. mucus, which typically traps particles in the lungs, builds up when the airways swell. Mucus is frequently infected, and injured alveoli lose some of their flexibility and surface area.

Hence, smoking is injurious to health.
