(3) annelids have nephridia which have a tubule with cilia. Flatworm classification related to their digestive system. Excretory cells known as flame cells developed in flatworms, while nephridia developed as excretory cells in annelids.
The Excretory Structure In Earthworm Is The A.
Osmoregulation in flatworms has not been demonstrated conclusively, but is thought to take place in the protonephridia. Platyhelminthes is the largest phylum of animals which do not have body cavities. They have a cluster of cilia that propel waste matter down the tubules and out of the body.

These cells move fluid within the protone phridia. Excretory system consists of nephridia as excretory organ which is analogous to kidney of vertebrates. As fluid passes down the tubule, solutes are reabsorbed and returned to the body fluids.
The Cells In The Tubules Are Called Flame Cells;
The cells in the tubules are called flame cells; (3) annelids have nephridia which have a tubule with cilia. Excretion occurs through a pore called the nephridiopore.
Flatworms Have An Excretory System With A Network Of Tubules Throughout The Body That Open To The Environment And Nearby Flame Cells, Whose Cilia Beat To Direct Waste Fluids Concentrated In The Tubules Out Of The Body.
Westblad, 1923), by the body wall, by exocytosis of vesicles such as some of those found in the excretory system, and by the protonephridial system. Nephridia remove metabolic wastes from an animal's body.
