Calculate the amount of tar taken in each day.

Case-Study Application Questions. 1 Based on the information that you gained in the case study, explain why smokers are often plagued by a cough. 2 Why is the slowing of the cilia lining the bronchi especially dangerous? 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 .

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.
