Step-by-step explanation:
Types of Intestinal Parasites
Intestinal parasites can be classified into three groups: nematodes (roundworms), cestodes (tapeworms), and trematodes (flukes). Nematodes include common parasites such as roundworms, pinworms, hookworms, and whipworms. Cestodes include tapeworms found in undercooked meat, such as beef, pork, and fish tapeworms. Trematodes are flukes that are located in specific body sites. These parasites can cause serious infections, but many are well-adapted to the human host and may not show obvious symptoms.
