Sponges have a water based circulatory system, a combination of the natural flow of water around and through them, plus a kind of hydrodynamic suction, where a slightly faster flow of water at their top portions sucks water through from the bottom, plus the collective wriggling action of flagellated cells on the surface of their bodies which creates a water current through the pores of the sponge.
Gases dissolved in the water enter and leave the sponge cells by diffusion.
