A roundworm has a complete digestive tract. It is a deuterostome. The planarian ingests food with one opening and excretes with the same hole... I'd say I'd rather be a roundworm due to that little detail... Wouldn't you?
A roundworm has an open nervous system.

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!
Roundworm infections are diseases of the digestive tract and other organ systems caused by nematodes. Nematodes are parasitic worms with long, cylindrical bodies.
The most common symptom of having a roundworm infestation in the digestive tract would be stomach cramps and asthma-like symptoms. Also you will find roundworms in your stool should you have an infestation.

Any of several worms of the phylum Nematoda, having unsegmented, cylindrical bodies, often narrowing at each end, and including parasitic forms such as the hookworm and pinworm. Also called roundworm.
The nervous system of a roundworm consists of a simple structure with a nerve ring around the pharynx and nerve cords that run along the length of the body. It includes sensory neurons, motor neurons, and interneurons that help coordinate movement and responses to the environment. The nervous system of a roundworm is relatively basic compared to more complex organisms.
