Answer:
The upper respiratory system includes the nasal cavity (nose), the pharynx and larynx.
Explanation:
Air enters the body through the nose or mouth, this moistens and warms the air that enters since cold dry air will irritate the lungs. The air then travels down the voice box and down the windpipe.
R- Rest (try to stay off of the injury for a few days)
I-Ice (ice the injury multiple times a day, but not directly to the skin).
C-Compress (compress the injured area with a elastic bandage, for example).
E-Elevate (elevate the injury adequately above the heart on a pillow).
hope this helps
