do earthworms have heart and blood? Explain.
kaviramesh203:
Heartbeats: Worms don't have just one heart. They have FIVE! But their hearts and circulatory system aren't as complicated as ours -- maybe because their blood doesn't have to go to so many body parts. Moving around: Worms have two kinds of muscles beneath their skin.

Answer:
yes, the earth worm circulates blood exclusively through vessels. there are three main vessels that supply the blood to organs within the earthworm. these vessels are the aortic arches dorsal blood vessel, and ventral blood vessels. the aortic arches function like a human heart.
