Nematodes do not have segmented bodies like annelid do.
The phylum that has a body plan that is essentially a tube within a tube is the Phylum Platyhelminthes, which includes flatworms. They have a simple body structure with a digestive tract that is a tube running from mouth to anus along the central axis of their body.
The phylum most closely related to arthropods would be the phylum Nematoda. This relationship is based on shared ancestral characteristics, such as the presence of a tube-within-a-tube body plan and bilateral symmetry.
Animals with a segmented body plan belong to the phyla Arthropoda, Annelida, and Chordata. Segmentation involves the repetition of body units along the length of the organism, which can be seen in arthropods with their jointed limbs, annelids with their repeated segments, and chordates during embryonic development.
A segmented body plan is characterized by the division of the body into repetitive segments, each of which may have similar or specialized structures. This arrangement allows for greater flexibility and mobility, as segments can move independently. An example of a phylum that includes animals with segmented bodies is Annelida, which consists of earthworms and leeches. Additionally, the phylum Arthropoda, which includes insects and crustaceans, also exhibits segmentation in its body structure.
