Earthworms have five pairs of hearts that pump blood throughout their bodies. They also have no lungs! (:
The hearts that worm's have are very different from the heart's that humans have. The worm equivalent of a heart is called the aortic arch and does not contain chambers or valves, and does not get oxygen-rich blood to the lungs. The aortic arches simply pump blood throughout the worm's body.
