  1. Nematodes By: Madi, Tyler, and Savanna "Spongebob Nematodes." YouTube. YouTube, n.d. Web. 04 Oct. 2014. <http://www.youtube.com/watch?v=X1YiIiPUQR8>.

  2. Body shape and movement • Bilaterally symmetrical • Move by thrashing and contraction of longitude muscles • http://www.youtube.com/watch?v=wCGNKAtsnMQ&feature=player_detailpage

  3. Nervous systems • Do have a nervous system • Rings of nervous tissue around pharynx • Runs along the dorsal and ventral sides of the nematodes "Taxonomy by TU72_834." Taxonomy by TU72_834. N.p., n.d. Web. 04 Oct. 2014. <http://vichakarn.triamudom.ac.th/comtech/studentproject/sci/taxonomy1/animalia.html>.

  4. Digestive system • One way digestive system • Opening to take in food and another expels wasteruns the length of the body "Flatworms and Roundworms." Flatworms and Roundworms. N.p., n.d. Web. 04 Oct. 2014. <http://www.k-state.edu/organismic/flatworms_and_roundworms.htm>.

  5. Excretory system • Excretory system is present • Series of excretory tubes • Ends in excretory pores "FAQs on Freshwater Worm Parasitic Diseases: Roundworms/Nematodes (Camallanus Esp.)." FAQs on Freshwater Worm Parasitic Diseases: Roundworms/Nematodes (Camallanus Esp.). N.p., n.d. Web. 04 Oct. 2014. <http://www.wetwebmedia.com/fwsubwebindex/nematodesfwf.htm>.

  6. Circulatory system • Nematodes have no heart or blood vessels so they have to get nutrients through there bodies in other ways. • They absorb nutrients through there skin using osmosis. "Your Name Your Major." Your Name Your Major. N.p., n.d. Web. 04 Oct. 2014. <http://bioweb.uwlax.edu/bio203/s2009/maiers_andr/Habitat.htm>.

  7. Respiratory system • Nematodes receive oxygen through there skin • Diffusion allows oxygen to even out inside their bodies "Respiratory System." Respiratory System. N.p., n.d. Web. 04 Oct. 2014. <http://rspp.weebly.com/>.

  8. Support system • No skeletal system • Cells together to make tissues to make up body exterior • Aquatic nematodes get support from water http://www.ucmp.berkeley.edu/phyla/ecdysozoa/nematoda.html http://bioweb.uwlax.edu/bio203/s2009/maiers_andr/Habitat.htm

  9. Reproductive system • Nematodes reproduce sexually. • Male has amoeboid sperm • Copulatory spicules- dilate the vulva and can also serve as a canal for the spermatozoa • http://www.hhmi.org/biointeractive/amoeboid-sperm-c-elegans

  10. Class: Ascaris • Common in many human population around the world. • Particularly in tropical and subtropical countries. • Likes warm summers with high rainfall. • Small amount- allergic reaction • Large amount- cough, chest pain, digestive dissorders "Flatworms and Roundworms." Flatworms and Roundworms. N.p., n.d. Web. 04 Oct. 2014. http://www.k-state.edu/organismic/flatworms_and_roundworms.htm.

  11. Class: Hookworm • By walking barefoot • In soil contaminated with feces. • Effects are- itchy rash, diarrhea, stomach pain, cramps, nausea, low red blood count (aka anemia) "Celebrate the American Hookworm!" Nature Afield Notes on Biophilia. N.p., n.d. Web. 04 Oct. 2014. <http://natureafield.com/celebrate-the-american-hookworm/>.

  12. Class: filaria • Mosquitos give them to humans through there bites • Thickens skin and underlining tissues due to blockage of the vessels of the lymphatic system "Filariasis - Causes, Symptoms, Diagnosis and Treatment , FAQs ."Medindia. N.p., n.d. Web. 04 Oct. 2014. http://www.medindia.net/patients/patientinfo/filariasis.htm>. "The LymphSystem." : Cancer aticResearch UK : CancerHelp UK. N.p., n.d. Web. 04 Oct. 2014. <http://www.cancerresearchuk.org/about-cancer/cancers-in-general/what-is-cancer/body/the-lymphatic-system>.

  13. Other phylum facts • Called roundworms- bodies are cylindrical in shape • Nematodes live in the soil, water, and animals • Parasites- organisms that live on or in an organism of another species. Harms the host as it obtains nutrients "Viral Fountain." Viral Fountain. N.p., n.d. Web. 04 Oct. 2014. <http://viralfountain.com/category/health/>.

  14. Important advancement • Nematodes were the first to have a body cavity • Separates the parts of the organism into different areas "Animals III - Pseudocoelomates, Mollusks, and Annelids." Courses. N.p., n.d. Web. 04 Oct. 2014.
