Nothing special, just the wall of your abdomen. When you were inside
your mother's womb, it was hooked up to your embryonic blood system. 
This was done via the placenta.  On the maternal side, the placental
is attached to the mother's blood system, and on the fetal side, the
fetus's blood system.  All nutrients needed for fetal growth pass
through the placental to the umbilical cord to the fetus, and all
wastes go the opposite way.

When the heart starts to pump the blood after birth, the placental
connection isn't needed anymore.
