BODY SHAPE AND MOVEMENT

• Bilaterally symmetrical

• Move by thrashing and contraction of longitude muscles

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

• One way digestive system

• Opening to take in food and another expels wasteruns the length of the body

EXCRETORY SYSTEM

• Excretory system is present

• Series of excretory tubes

• Ends in excretory pores

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

• Nematodes receive oxygen through there skin

• Diffusion allows oxygen to even out inside their bodies

SUPPORT SYSTEM

• No skeletal system

• Cells together to make tissues to make up body exterior

• Aquatic nematodes get support from water

REPRODUCTIVE SYSTEM

• Nematodes reproduce sexually.

• Male has amoeboid sperm

• Copulatory spicules- dilate the vulva and can also serve as a canal for the spermatozoa

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

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)

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

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

IMPORTANT ADVANCEMENT

• Nematodes were the first to have a body cavity

• Separates the parts of the organism into different areas
