Endoparasites (a parasite that lives in the internal organs or tissues of its host) produce some compounds of anti-enzymes which defuse or inactivate the host's digestive enzymes.
Endoparasites maintain their osmotic concentration equivalent to or significantly lower than the host cell for easy absorption of host water and nutrients.
There are three main classes of parasites involve:
Protozoa include Plasmodium, the single-celled organism. A protozoa inside the host can only replicate, or split.
Helminths parasites are worms.
Ectoparasites: These are living on, not in their hosts.
