You are correct, there are only three worm phyla. So the key to the question was that your worm is segmented. All segmented worms belong to Phylum Annelida.
The endocrine & Digestive.
I am in 7th grade and we are learning about segmented worms. i got this information from my textbook. Worms have a tube like body with a bristle like structure called setae. Setae help keep worms in the soil and help them move. Segmented worms also have bilateral symmetry, a body cavity that holds the organs, and two openings -- mouth and an anus.
Round worms belong to phylum Ascelminthes (nemathelminthes) ,a higher phylum than sponges (poriferans) and coelenterones.Round worms are bilaterally symmetric.which is considered as a superior quality.Also they are triploblastic and has a well developed muscular pharyx.Sexual dimorphism is also seen in round worms.
Flatworms are divided into two groups, parasitic and nonparasitic. The parasitic types, which live off of other organisms, consist of Cestoda, Trematoda, and Monogenea flatworms.
The digestive system processes your food and extracts nutrients from it.
The first of the two functions of the digestive system is to break down nutrients. The second function is the absorption of nutrients.

The Digestive System and the Renal System.
Digestive system and reespiratory system
Bob Martin Dewormer is designed to kill the round worms contracted by horses. It usually takes a day or two to kill every roundworm.
The pharynx belongs to both the respiratory system and the digestive system. It serves as a passageway for air to travel from the mouth and nose to the trachea and for food to travel from the mouth to the esophagus.
