body shape and movement
Body shape and movement
  • Bilaterally symmetrical
  • Move by thrashing and contraction of longitude muscles
  • http://www.youtube.com/watch?v=wCGNKAtsnMQ&feature=player_detailpage
nervous systems
Nervous systems
  • Do have a nervous system
  • Rings of nervous tissue around pharynx
  • Runs along the dorsal and ventral sides of the nematodes

digestive system
Digestive system
  • One way digestive system
  • Opening to take in food and another expels wasteruns the length of the body

circulatory system
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.

respiratory system
Respiratory system
  • Nematodes receive oxygen through there skin
  • Diffusion allows oxygen to even out inside their bodies

support system
Support system
  • No skeletal system
  • Cells together to make tissues to make up body exterior
  • Aquatic nematodes get support from water

reproductive system
Reproductive system
  • Nematodes reproduce sexually.
  • Male has amoeboid sperm
  • Copulatory spicules- dilate the vulva and can also serve as a canal for the spermatozoa

other phylum facts
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
