In the development cycle of flatworms, a change of hosts is observed. where does the developmental cycle of the hepatic fluke take place?

During its life cycle, a parasitic worm called the liver fluke changes two hosts:

Initially, it begins to parasitize in the body of a freshwater mollusk.
Then the released forms enter the gastrointestinal tract of cattle – it is bulls and cows that are the final host of this parasite, because it is in the body of these animals that sexual reproduction of the hepatic fluke takes place.
An interesting point – a person for him can be the final owner if he uses dirty water.
