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

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.
