well Earthworms have closed circulatory system so hopefully that answers your question
Worms have a closed circulatory system because they inherited it from their ancestors.
yes they do
Example of closed Circulatory animals is worms
Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
yes
I don't know. You tell me.
segmented worms have a closed circulatory system.in a closed circulatory system, blood moves only within a connected network of tubes called blood vessels.
Segmented worms move by peristalsis. These are waves that flow through the body making the segmented worm turn and bend flexibly.
Frogs have a heart that has 3 chambers, and worms do not. Worms exchange gas from their blood through their skin, but frogs are not able to do this. Frogs have the same type of respiratory system as humans.
Obviously every creature needs a circulatory system. Just cuz its flat doesn't mean it doesn't have any circles in it. DuH.
Segmented worms have closed circulatory systems like humans. This means that blood is carried throughout the body in vessels: arteries, veins, and capillaries. So, like humans a segmented worm's circulatory system just carries blood through vessels.
