a coelomate animal has a body cavity that is completely lined by what kind of tissue in many animals?
undifferentiated
in amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm. organs formed inside the coelom can freely move, grow, and develop independently of the body wall while fluid in the peritoneum cushions and protects them from shocks.









































arthropods and most molluscs have a reduced (but still true) coelom, usually the pericardial cavity and the gonocoel. their principal body cavity is the "hemocoel" or "haeomocoel" of an open circulatory system, often derived from the blastocoel.

body cavity
pseudocoelomate animals have a pseudocoelom (literally “false cavity”), which is a fluid filled body cavity. tissue derived from mesoderm partly lines the fluid filled body cavity of these animals. thus, although organs are held in place loosely, they are not as well organized as in a coelomate. all pseudocoelomates are protostomes; however, not all protostomes are pseudocoelomates. an example of a pseudocoelomate is the roundworm. pseudocoelomate animals are also referred to as blastocoelomate.









































acoelomate animals, like flatworms, have no body cavity at all. semi-solid mesodermal tissues between the gut and body wall hold their organs in place.
