A pseudocoelom is a type of body cavity that is not fully lined with mesoderm, unlike a true coelom. It serves as a fluid-filled space that separates the digestive tract from the outer body wall, allowing for greater flexibility and movement of internal organs. This feature is particularly significant in certain groups, providing structural support and serving as a hydrostatic skeleton for organisms.
