The lungs and respiratory system allow us to breathe. They: Bring oxygen into our bodies (called inspiration, or inhalation). Send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
A form of oxygen called ozone is a pale blue gas that is explosive and poisonous. It is found in the upper atmosphere, and there it is helpful. It traps harmful rays from the sun and prevents them from reaching Earth’s surface.
The respiratory system is the body’s way of breathing in oxygen and breathing out carbon dioxide. Insects breathe through holes in the sides of their bodies. Fish and young amphibians have organs called gills to take in oxygen from water.
