pseudocoel
Quick Summary
The term "pseudocoelom" refers to a body cavity that is not a product of gastrulation and lacks a well-defined mesodermal lining. This cavity exists between the inner endoderm and the middle mesoderm body layers.12
Organisms possessing this type of body cavity are classified as pseudocoelomates. This group includes invertebrates like rotifers and nematodes. Unlike a true coelom, the pseudocoelom is not lined with a cellular peritoneal lining. In these organisms, muscular movements of the body can help circulate nutrients within the pseudocoelom.345
