Well if they are living then they will obviously have a brain, but to be honest with you i have never heard of a nematode in my entire life!

To respond to the above--not every living thing has a brain. For example, protists are unicellular organisms possessing all the qualifications of life, of which having a brain is not included. (Sensitivity to stimuli is a qualification, but you don't need a brain for such responses.) Sponges are also living organisms without a brain. Nematodes have a dense ring of nerves that serves as a "brain" of sorts, though it is not comparable to say a dog's or a human's.
One way platyhelminthes differs from nematodes is that they do not have an actual digestive system. Instead they take in the oxygen and nutrients they need through their flat bodies.
nematodes are literal living dead they can shut down their bodies functions and revive themselves if they want to
Yes, all organisms in phylum nematoda are multicellular.
Roundworm infections are diseases of the digestive tract and other organ systems caused by nematodes. Nematodes are parasitic worms with long, cylindrical bodies.
· They are also known as round worms. · They are triploblastic, bilateral, vermiform and pseudocoelomate · They have bodies that are covered in cuticles, which must be molted. · They have Amphids which are cephalic sense organs · Sense organs and sex lips surround their mouths. · They have a unique excretory system but no special circulatory or gas exchange systems. · They are gonochoristic.
The body system that the colon belongs to is the digestive system. The colon is also known as the large intestine.
Nematodes are characterized by their long, slender, unsegmented bodies covered in a tough cuticle, which gives them a cylindrical shape. They also have a simple digestive system, with a mouth and anus at opposite ends of their bodies. Additionally, nematodes have a hydrostatic skeleton, which helps them maintain their body shape and move efficiently.
Nematoda are worms with long, cylindrical bodies and round cross-sections. They have a pseudocoelom, complete digestive system, and exhibit bilateral symmetry. Nematodes are found in a variety of habitats and can be free-living or parasitic.
Well I do remember reading in my 'Life Science' textbook last year the roundworm has a 2 way digestive system. I believe it goes through the mouth, into the intestines, absorbed in through the body and out the other way. I know for sure a roundworm has a 2 way digestive system. I just read my homework, lol. It says on a worksheet, "Science Explorer Life Science" Roundworms have a two-way digestive system and open at both ends. Hope I helped!
All members of nematodes, or roundworms, share a basic set of characteristics: they have a long, cylindrical body that is tapered at both ends, a complete digestive system with a mouth and anus, and a tough, flexible cuticle that protects their bodies. Nematodes possess a pseudocoelom, which is a body cavity that is not completely lined by mesoderm, and they exhibit bilateral symmetry. Additionally, they are unsegmented and can be found in a variety of environments, including soil, freshwater, and marine habitats.
