The liver fluke is a parasitic trematode of the phylum Platyhelminthes.
Fasciola hepatica is another name for sheep liver fluke.
Digenetic organisms are organisms that use two host organisms to complete their life cycle.
Liver flukes spend their entire life cycle in two hosts.
They live as an internal parasite in vertebrates during their sexual reproduction phase and as an asexual parasite in molluscs when they are present.
As a result, they are digenetic organisms.
Furthermore, liver flukes are pathogenic because they can move through human blood circulation, bile ducts, gallbladders, and livers, causing pathogenic lesions.
These lesions have the potential to cause pathogenic diseases.
