respiratory systems
Oxygen exchange organs
Respiratory systems are the organs and structures that allow organisms to exchange gases with their environment—taking in oxygen and expelling carbon dioxide.
In humans and other mammals, this includes the lungs, airways, and diaphragm.
Fish have gills, insects have tracheal tubes.
The term appears in biology and medicine: The respiratory system is vulnerable to airborne pathogens.
