The circulatory fluid (I don't think its blood) and respiratory pigments circulate in vessels and never leave the vessels, much like that of humans and other mammals. This is in contrast to the circulatory system of insects, where the fluid (haemolymph) goes from the heart, through a vessel and then flows out to surround or 'bathe' the organs

How is the circulatory system of segmented worms unique among worms?
Segmented worms move by peristalsis. These are waves that flow through the body making the segmented worm turn and bend flexibly.
A segmented worm's circulatory system does what?
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.
What characteristics of a segmented worm make it a worm?
Annelids are bilaterally symmetric and triploblastic protostomes with a coelom, closed circulatory system and true segmentation. Their segmented bodies and coelom have given them evolutionary advantages over other worms.
What kinds of body systems do segmented worms have?
I am in 7th grade and we are learning about segmented worms. i got this information from my textbook. Worms have a tube like body with a bristle like structure called setae. Setae help keep worms in the soil and help them move. Segmented worms also have bilateral symmetry, a body cavity that holds the organs, and two openings -- mouth and an anus.
What type of circulatory system does a tapeworm have?
segmented worms have a closed circulatory system.in a closed circulatory system, blood moves only within a connected network of tubes called blood vessels.
Why is the segmented structure of segmented worms important?
The segmented structure of segmented worms allows for greater flexibility and movement due to the ability of each segment to move independently. This allows segmented worms to navigate through their environment more efficiently. Additionally, the segmentation provides redundancy in case of damage to one segment, as the worm can still function with the other segments.
What type of digestive system do segmented worms have?
none
Which phyla have segmented bodies and a close blood system?
phulum Annelida and phylum Arthropoda have segmented bodies and only phylum Annelida has closed circulatory system while Arthropodes have open circulatory system
Are ticks segmented worms?
No, ticks are not segmented worms.
Do worms have a closed circulatory system?
yes they do
Why does a worm have a closed circulatory system?
Worms have a closed circulatory system because they inherited it from their ancestors.
Animals with a closed circulatory system?
Example of closed Circulatory animals is worms
