RLH replies:

The placenta is a feeding and excretory device derived from embryonic
trophoblastic tissue and as such the placenta is the critical link between
the fetus and maternal provisions.  Pregnancy comes to term just as the
placenta begins to atrophy, it is at this point that the fetus makes the
transition to neonate.  Usually the decidua (remnants of the failing
placenta) are sloughed from the uterus within hours following birth and
maternal healing begins.

Metaphorically, the placenta dies as the child is born.  Symbolically,
cutting the placental cord marks the birth of a human infant-separating the
dying vestiges of gestation from the living, breathing neonate.  The fetus
is dead, long live the human infant.
