Taenia A member of phylum Platyhelminthes. They are acoelomate and excrete by flame cells or Protonephridia. Paramoecium A protozoan member. They have contractile vacuoles for osmoregulation. Periplaneta Malpighian tubules are the excretory structures of most of the insects including cockroaches. Malpighian tubules help in the removal of nitrogenous wastes and osmoregulation. In addition, the fat body, nephrocytes and urecose glands also help in excretion. Pheretima Nephridia are the tubular excretory structures of earthworms and other annelids. Nephridia help to remove nitrogenous wastes and maintain a fluid and ionic balance.
