Arthropods have an open circulatory system, with organs in the internal body cavity (hemocoel) and cells bathed in hemolymph. The fluid drains into open pores for recirculation usually by a dorsal tube acting in the role of a heart.
Not all arthropods use hemolymph for oxygenation; insects for example oxygenate tissues directly via tubules connected through vents (spiracles) to the atmosphere.
