What is this?
Respiration in earthworms is how they take in the air they need to live and get rid of the air they don't need. Unlike humans, earthworms breathe through their moist skin, absorbing oxygen directly from the soil or water around them. This special way of breathing helps them stay alive and move around underground.
Key Parts to Explore
Moist Skin
This thin, wet outer layer is where the earthworm takes in oxygen and releases carbon dioxide.
Mucus Layer
A slimy coating on the skin keeps it moist, which is essential for breathing to happen.
Blood Vessels
Tiny tubes just under the skin pick up oxygen and carry it to all parts of the earthworm's body.
Surrounding Soil
The damp soil around the earthworm provides the oxygen it needs to breathe.
Did You Know?
Did you know that earthworms don't have lungs like us, but breathe right through their moist skin instead?
