archenteron
Quick Summary
The archenteron is the primitive gut cavity that forms during gastrulation in an embryo. This process is a crucial stage in embryonic development where the single-layered blastula reorganizes into three germ layers: the ectoderm, mesoderm, and endoderm.12
The archenteron forms when cells from the blastula push inward, creating a double-walled cup. The inner lining of this cup develops into the endoderm and mesoderm, while the outer layer becomes the ectoderm. The archenteron eventually gives rise to the hollow core of the alimentary canal. The opening of the archenteron to the exterior is called the blastopore, which may develop into the mouth or anus depending on the animal group.23

The archenteron eventually becomes the cavity of the digestive tract, and the blastopore becomes the anus; the mouth arises as a new opening.
