Ctenophora-comb jellies-long tentacles, combs are rows of fused cilia, some are bioluminescent colloblasts-cells containing vacuoles with a sticky thread-like protein that burst open and captures food particles

Protonephridia flame cell metanephridia
Flame cell found in Platyhelminthes pulls in water and pumps it out with cilia no concentration of waste. Protonephridia found in Molluska several flame cells with some transport of good substances out of the tube loses lots of water little concentration of waste
Metanephridia take in coelomic fluid and reabsorb the nutrients and water which are then picked up by the associated blood vessels thus they concentrate the nitrogenous waste found in Annelids
