12. Types of Nematodes

13. Arcaris Common intestinal parasite
Poor sanitation, human feces fertilizer
Feed on nutrients in human guts
Abdominal pain
Pulmonary Migrate

14. HookWorm Intestinal parasite Poor sanitation, human feces fertilizer
Penetrate feet skin
Block intestines
Feeds on nutrients in intestines

15. Trichinella Found in pigs, bears, horses, and humans.
Commonly contracted from raw or undercooked pork
Flu like symptoms
Most cases untreated; end in heart problems/ death

16. Filaria Mosquito Bites Blood vessels feed on nutrients in blood
Tropical areas
Lymph nodes swell (elephantiasis)

17. Elephantiasis

18. Location Can live in all environments
Common in unsanitary locations, 3rd world countries
Soil and aquatic areas

19. Roundworms
Long, narrow, cylinder bodies
tapered at each end.

20. Parasite
Organism that lives off another organism
Harms the host

21. Body Cavity Keep important organs protected
Pseudocoelom - fluid filled body cavity
Bathes internal organs

22. You are not a Nematoda

By spending less time moving in the soil, a nematode can reduce its chance of "running into" a predator or pathogen. Some plant nematodes spend most of their time in the soil (ectoparasites) and others are mostly contained within the plant tissu. “Introduction to Plant-Parasitic Nematodes.” Introduction to Plant-Parasitic Nematodes,
