An embryo during the late stages of development is known as a fetus.
A palingenesis is the apparent repetition during the development of an embryo, of changes which occurred previously in the evolution of its species, or an instance of rebirth or regeneration.

During development, an embryo is embedded in the the endometrium during the first week of pregnancy. The endometrium is the innermost muccous membrage of the uterus. The embryo becomes implanted in it, then the surrounding tissue forms sinuses that exchange nutrients and later becomes the placenta.

During the period of the embryo, the four key changes that take place include: differentiation of cells into specialized tissues and organs, establishment of the basic body plan, development of major organ systems, and initiation of rudimentary limb and facial features.
This may be wrong, but I believe that it comes with the embryo it's self and provides nutrients.
