Answer to Question 1

C
The body's response to chronic hypoxemia is to produce too many red blood cells; this is polycythemia. Lack of iron in the diet could lead to anemia.

Answer to Question 2

A
Emphysema is defined pathologically as the presence of permanent enlargement of the airspaces distal to the terminal bronchioles accompanied by destruction of the alveolar walls.
