Answer to Question 1

alveoli

Rationale: The alveoli are the small air sacs positioned at the end of the terminal bronchioles. Oxygen and carbon dioxide exchange occurs in the elastic air sacs known as alveoli.

Answer to Question 2

affected orbit

Rationale: The affected orbit is imaged closest to the IR as part of the lateral orbit projection. The lateral will demonstrate anterior to posterior displacement.
