The mechanism of protection of parasitic nematode from digestive enzymes of its host. Introduction: Parasites are the disease-causing organism, which may further be of two types depending upon their living nature on their host, i.e., endo-parasites (resides within the host) and ecto-parasites (resides on the host). Nematodes also known as round-worms or the Aschelminthes. These are the triploblastic, bilaterally symmetrical, and unsegmented worms. They lack respiratory and circulatory system. Nematodes are pseudocoelomates (not lined by mesodermal epithelium). They are mostly free-living, aquatic, or parasitic (both on plants and animals).

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
