Question 4

Lung cancer occurs slightly more frequently in the right lung than in the left lung (about 53% versus 47% of the time). The most logical explanation for this is that

Accepted Answer

A)  the tissue of the right lung is more susceptible to carcinogens. 
B)  the right nostril is closed more often than the left one, so it blocks the exhalation of cigarette smoke and causes smoke to back up into the right lung. 
C)  most people are right-handed, so everything affects the right side of the body more intensely. 
D)  the right primary bronchus is wider than the left one (and the right lung is larger than the left lung), so the right lung receives slightly more carcinogenic cigarette smoke with each puff.

Question 5

In emphysema, the alveoli become enlarged due to deterioration of the alveolar walls. How does this lead to a lack of oxygen?

D)  The alveoli walls become impermeable to oxygen as they enlarge.
