Cancer usually begins in the bronchi or bronchioles. Components of cigarette smoke contribute to the development of cancerous tumours. Study the four diagrams below, which show the development and progression of lung cancer.

Cilia sweep away the debris trapped by the mucus. Unfortunately, the tar found in cigarette smoke slows the action of the cilia. The sludge-like tar becomes trapped in the mucus. b) Why does the build-up of tar in the bronchi limit air flow?
