• The respiratory system is made up of the following organs12345:
• Nose
• Mouth
• Throat (pharynx)
• Voice box (larynx)
• Windpipe (trachea)
• Air enters the respiratory system through the nose or the mouth, and passes
through the throat, where the pharynx and larynx are, into the trachea. The
trachea then divides into two tubes called bronchi that enter each of your two
lungs, the right and left lungs.
