celom

body cavity, especially the original cavity in the mammalian embryo between the somatopleure and splanchnopleure, which is both intra- and extraembryonic; the principal cavities of the trunk, the pericardial, pleural and peritoneal sacs, arise from the intraembryonic portion.

celom partitioning
separation of the pleural and pericardial sacs in the embryo is established by the pleuropericardial septum formed by the fusion and extension of the pleuropericardial folds.
