Usage Examples

The protonephridia are complex structures found in the phylum Platyhelminthes.
In platyhelminths, the protonephridia are both osmoregulatory and excretory in function.
They are rich in the parasitic lophotrochozoan Turbellaria and cephalmetra partly, while the simplified systems are in acoels.
Shedding of anterior parts of plathelminths is rare but has distinct protonephridial distribution.
In Acoela, the distribution of protonephridia doesn’t follow the existing pattern.
