This animation shows the development of the extraembryonic coeloms. In humans, during week 8 the chorionic cavity is lost by fusion with the expanding amniotic cavity.

Note that as the yolk sac (yellow) is continuous with the midgut you can also follow development of the gastrointestinal tract regions of foregut, midgut and hindgut.

Embryo and placental membranes are shown to the left and the developing placenta is shown to the right.

yellow - outside embryo yolk sac (circular balloon) and inside embryo gastrointestinal tract regions (foregut, midgut and hindgut)
blue - amniotic cavity
white - chorionic cavity surrounding amnion and yolk sac
