Animation (left) shows the events following implantation and focuses on changes in the the spaces surrounding the embryonic disc, the extraembryonic coelom.

The blastoceol cavity is converted into two separate spaces: the yolk sac and the chorionic cavity.

The third space lies above the epiblast, the amniotic cavity.

blue - epiblast layer
yellow - hypoblast layer
red cells - extraembryonic mesoderm layer
green - trophoblast layer
red spaces - blood-filled spaces, maternal lacunae
white cells - (left) endometrial gland (right) endometrial epithelium
