Answer:
Your lungs take in oxygen and give off carbon dioxide. Worms do not have lungs but I breathe through my skin. I take in oxygen through my skin and it goes right into my bloodstream.

Answer:
Earthworms do not have lungs; instead, they breathe through their skin. Their skin needs to stay moist to allow the passage of dissolved oxygen into their bloodstream. Earthworm skin is coated with mucus, and they need to live in a humid, moist environment.
