Primary interventricular foramen
In human embryology, the primary interventricular foramen is a temporary opening between the developing ventricles of the heart. The ventricles arise as a single cavity that is divided by the developing interventricular septum. Before the septum closes completely, the remaining opening between the two ventricles is termed the interventricular foramen.
