respiratory system
Lungs and airways
The respiratory system is the set of organs that brings air into the body and expels it—nose, throat, windpipe, and lungs in humans.
Oxygen passes into the blood while carbon dioxide passes out.
Smoking damages the respiratory system.
The term applies broadly to gas-exchange mechanisms across species, from gills to spiracles.
