A metanephridium (meta = "after") is a type of excretory gland found in many types of invertebrates such as annelids, arthropods and mollusca. (In mollusca, it is known as the Bojanus organ.)
Protonephridia are made up of many flame cells. In the flame cells, there are cilia at the 'tips'. They beat, creating a sort ..
Protonephridia and Metanephridia–Their relation within the Bilateria. Two different kinds of nephridia occur within the Bilateria, protonephridia closed up by a terminal cell and metanephridia opening into the coelomic cavity. Both initially filter and subsequently modify intercellular fluids

Two different kinds of nephridia occur within the Bilateria protonephridia closed up by a terminal cell and metanephridia opening into the coelomic cavity. Whereas metanephridia are strictly correlated to a coelom proto-nephria occur in a coelomate as well as in coelomate organisms.
