3 Survey different smokers and find out how many cigarettes they smoke in one day. Most
cigarettes contain about 15 mg of tar, but it should be noted that only 75% of the tar is
absorbed. Calculate the amount of tar taken in each day. Show your calculations.
4. Nicotine, one of the components of cigarettes, slows cilia" lining the respiratory tract,
causes blood vessels to constrict, and increases heart rate. Another component of cigarette
smoke is carbon monoxide. As you have read, carbon monoxide competes with oxygen for
binding sites on the hemoglobin molecule found in red blood cells. Analyse the data
presented, and describe the potential dangers associated with smoking.

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.
