Question:
Why do worms have more than one heart? Is there a record for the most hearts in a worm, if so what? If you could answer my question soon that would be very nice.


Replies:
Worms don't have the same kind of heart that animals do. Their "hearts" are really just bands of tissue that surround their vascular system (and digestive system). They have two vessels that are connected: one on the back and one on the belly and the bands pump to keep stuff moving.Our hearts are muscular cavities that actually fill with blood and squeeze that blood out and around the body.
