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.
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.
