Yes. Arthropods have body cavities (coelomates); their main internal cavity is a hemocoel, which accommodates their internal organs and through which their blood circulates - they have open circulatory systems. Arthopods come from a lineage of animals that have a coelom, a membrane-lined cavity between the gut and the body wall that accommodates the internal organs. The coelom of the arthropod is reduced to small areas around the reproductive and excretory systems. Visit http://smackers0609.blogspot.com/Yes.
