WebMay 28, 2024 · What is the function of the blastopore? Blastopore Functions. It plays an important role in organizing and defining the germ layers. Through this layer, there is a communication between the embryo and the outside environment in the womb. There is also a transfer of the necessary fluids until the gastrulation period lasts. WebArchenteron. The archenteron, also called the gastrocoel or the primitive digestive tube, is the internal cavity of the primitive gastrointestinal tract that forms during gastrulation in a developing animal embryo. It develops into the endoderm and mesoderm of the animal.
