What is a roundworms coelom?

Roundworms, or nematodes, possess a pseudocoelom, which is a body cavity that is not completely lined by mesoderm. This pseudocoelom serves as a hydrostatic skeleton, providing structural support and facilitating movement through the contraction of muscles. Unlike true coeloms found in other organisms, the pseudocoelom is located between the body wall and the digestive tract, allowing for the efficient transport of nutrients and waste. Overall, the pseudocoelom is integral to the roundworm's physiology and movement.
