Annelida- The ringed worm phylum
The Neried Worm The Earth Worm The Leech
These 3 worms all have the same basic excretory systems. They all have organs called metanephridia. This is a funnel like organ that is in the middle of the body cavity that collects the waste. This organ is connected to a duct that carries waste to openings called Nephrostones. Then the waste leaves the body through a pore called the Nephridipore.
