The earthworm needs oxygen for his vital body processes, just as we do  Also like us, he takes it from the air and returns waste carbon dioxide  However, has breathing organs are very different from ours  He has no nose and no lungs with which to breathe air in and out  However he is a very small animal and he does not need much oxygen to keep his body processes going 

This oxygen is taken in by the worm is moist skin  It comes in contact with the finest of fine blood vessels near the surface  One of the vital organs inside his small body acts like a simplified heart to pump the oxygen‑rich blood to the tissues
