Nematode-Ascaris Parasite that lives in the intestines of pigs, horses and humans. Feed on the food that passes through the intestines of there host. Females grow up to 30cm(1ft) Produce up to 200,000 eggs everyday If severely infected the larvae in the lungs can back air pressure and cause bleeding from small blood vessels.

Nematode-hookworms size from 5 to 11 millimetres (0.2 to 0.4 inch) Hookworms- a small roundworm that enters the bodies of human beings and some animals through the skin. size from 5 to 11 millimetres (0.2 to 0.4 inch) Live as parasites in the intestines. Sucks up blood and tissue fluids. Cause anemia (a shortage of red blood cells). cause an itchy, red patch on human skin called creeping eruption

Nematode-Trichina Trichina- a small roundworm that causes the disease trichinosis measure between 1.4 mm and 1.6 mm long Parasite- feed on animals. Adults live embedded in the walls of the hosts intestine The Produe larvae that travel through the bloodstream to the muscle where they form cysts. People become infected when they eat undercooked meat usually pork that is contaminated with cysts. After they are eaten, the cysts release the larvae (early form of the worms) which burrow into the intestinal wall and mature into adults.

Trichinella Kingdom Animalia Phylum Nematoda Class Adenophorea Order Trichocephalida Family Trichinellidae Genus Trichinella

Nematode-Pinworm Pinworm- Most common round parasite of humans in the united states Infects 16% of adults 30% kids Don’t cause any real diseases 5-10mm (0.2-0.4in)in length Females migrate out and lay eggs which become infectious in soil or in an intermediate host before infecting humans

Nematode-Filarial worm Disease-cause-round worms that infect over 250 million people in tropical countries Most dangerous filarial worms in the lymphatic system 100mm(4in) Blocked-the lymphatic vessels causing fluid to accumulate in the limbs. They can be seen in the blood near the body surface of the host (the animal in which the larvae live).
