The anatomy of a nematode, or roundworm, is characterized by a cylindrical, unsegmented body that is tapered at both ends. They possess a complete digestive system with a mouth, pharynx, intestine, and anus, and lack a circulatory system, relying on diffusion for nutrient transport. Their body is covered by a tough cuticle, and they have a simple nervous system with a nerve ring and longitudinal cords. Nematodes also exhibit sexual dimorphism, with distinct male and female forms.
