In the first developmental stage of the embryo, you have the ball of cells. In this ball of cells you have cavity filled with fluid called amniotic fluid. This fluid sac separates the embryo, from the outer non-embryo cells. Later on it encloses the fetus in amniotic fluid to give amniotic sac. This sac is attached to uterus from inside.
