Phylum Platyhelminthes Flatworms. Parasitic. Acoelomates. Tripoblastic. Dorsoventrally flattened- greater S.A to respire by diffusion. Tegument- surficial covering of multicellular organism Parenchyma- loosely arranged mass of fibers and cells Phylum Platyhelminthes- Classes Turbellaria. Trematoda. Monogenea. Cestoidea. Digenea Subclass to class Trematoda. Parasitize all classes of vertebrates. Develops in at least two hosts. First host is usually a mollusk (snail), or very rare...
