Platyhelminthes, commonly known as flatworms, exhibit a simple body plan characterized by a flattened, bilaterally symmetrical shape. They lack a true coelom, have a soft body, and possess three tissue layers: ectoderm, mesoderm, and endoderm. Their bodies often feature a distinct head region with sensory organs and a gastrovascular cavity for digestion, which serves both nutrient absorption and waste removal. Platyhelminthes typically exhibit a lack of a specialized respiratory and circulatory system, relying on diffusion for gas exchange.
