a. Because Mr. B's right lung collapsed, his heart moved over into the empty space.
b. The air in Mr. B's chest is making his heart collapse - an emergency!
c. Mr. B's heart has not really moved, but the air in his chest is making it sound different.
d. Because the left side of Mr. B's chest is filling up with air, the organs in his chest are being pushed over to the right.
