Answer to Question 1

epiglottis

Rationale: The epiglottis serves to close and seal off the larynx to prevent aspiration during the act of swallowing.

Answer to Question 2

SID

Rationale: Beam intensity is relative to field size. As SID increases, the beam intensity is spread over a larger surface area resulting in less beam reaching the image receptor.
