archenteron The main cavity of an embryo in the gastrula stage; it is lined with endoderm and represents the future digestive cavity.
archinephric archi = beginning, original; nephros = kidney.

However, in protostomes the initial opening (the archenteron) develops into the mouth, and an anus forms separately. In deuterostomes this is reversed.

epithelial cells found at the initial site of gastrulation, lining the initial archenteron, that temporarily become bottle-shaped; they maintain contact with the outer surface of the embryo, but the majority of the cell is inside the embryo.
