nephridium
nephridium In many invertebrates, an organ probably concerned with excretion and the regulation of the water content of the body. It consists of a simple or branched tubule, lined with
cilia. Excretory products diffuse into the tubule and are wafted by the cilia through a nephridiopore leading to the exterior of the body. There are several types of nephridia. A protonephridium is a tubule with a blind inner end bearing a
flagellum or tuft of cilia, found in all
acoelomates and
pseudocoelomates, and in some
coelomates. A metanephridium is an unbranched tubule open at the inner end through a funnel (the
nephrostome), found in some coelomates.
