The intraembryonic coelom is the only cavity that persists in the mammal at term, which is why its name is often contracted to simply "coelomic cavity". Subdividing the coelomic cavity into compartments, for example, the pericardial cavity / pericardium, where the heart develops, simplifies discussion of the
