How does nutrients get to cells in a flatworms solid acoelomate body?

In flatworms, which are acoelomates, nutrients are absorbed directly from the environment through their moist skin and distributed to cells via diffusion. Their bodies are relatively thin, allowing for efficient nutrient exchange without specialized circulatory systems. The gastrovascular cavity also plays a role, as it helps in the digestion and distribution of nutrients throughout the body. Overall, the flatworm's simple body plan facilitates direct nutrient access to all cells.
