Define the following terms in animal health Intermediate host Definite host Cercariae?

Intermediate host: An intermediate host is a host in which a parasite goes through one or more of its developmental stages before reaching its definitive host. The parasite may undergo growth, reproduction, or other changes in the intermediate host before being transmitted to the definitive host.

Definite host: A definitive host is the host in which a parasite reaches sexual maturity and reproduces. This is the host in which the parasite completes its life cycle and is able to produce offspring that can infect other hosts.

Cercariae: Cercariae are a larval stage of certain parasitic flatworms, such as trematodes. They are released from the intermediate host and swim freely in water, seeking out a suitable definitive host to infect. Cercariae are typically covered in a protective outer layer and have specialized structures for penetrating the skin of their host.
