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.
