1. These groups have a reduced coelom , called a pseudocoelom. 2. In Protostomes, the coelom forms by a process known as schizocoely. 3. It sometimes partially protrudes the lining of its coelom through its mouth. 4. The species in this family infect the coelom of oligochetes. 5. This then leads to the formation of a coelom . 6. These pockets gradually expand to form the coelom . 7. Nutrients are transported throughout the coelom , including the mantle lobes, by cilia. 8. The new mesoderm then splits, creating the pocket-like cavity of the coelom . 9. The filtrate is deposited into the coelom . 10. It is always oriented towards the coelom .
