This office that they deport the same train of osmotic obligate distribute and the solvent f milds through a semi poriferous tissue layer from a section of low solute concentration to a region of high solute concentration.

Therefore, they can inhabit, mark and sustain constancy in their new environment when migrating. Circulation: They have an open circulatory system, marrow the blood does not dust entirely deep down vessels but is collected from the gills, handle through the heart, and released instantlyly into spaces in the tissues from which it returns to the gills and then to the heart. Such a blood-filled space is make love as a hemocoel (blood cavity). The hemocoel has largely replaced the coelom, which is fall to a small region around the heart and to the cavities of the organs of reproduction and excretion.
