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
