Do earth worms have 5 hearts?

User Avatar

Asked by Wiki User

An earthworm does not have any heart at all. But they do have an organ that acts similarly to a heart and is usually called a heart just for simplicity's sake, although is is also called an aortic arch. Earthworms have five of these arches. In between each arch is a gland that helps the worm digest calcium, which it gets from eating a lot of dirt. size The heart and calciferous gland section makes up less than five percent of an earthworm's total body length, no matter how big the individual worm gets.

Function

The aortic arches (hearts) help pump blood around the body of the earthworm in a similar way to animals that have only one multi-chambered heart. Worm "hearts" don't have chambers. Worms also don't have lungs. They absorb oxygen through their skin and then it gets into their blood vessels. The dorsal blood vessel does a bit of the pumping work, with the hearts helping to keep blood pressure steady.
