It nourishes the fetus while it is developing in the womb and is then expelled after the baby is born.
It also helps to protect the baby from infections because it keeps the mother's blood and baby's blood separate by acting as an effective filter.

Oxygen and nutrients pass from your blood supply into the placenta. ... Waste products from the baby, such as carbon dioxide, pass back along the umbilical cord to theplacenta and then into your bloodstream, for your body to dispose of them. Theplacenta produces hormones that help your baby grow and develop.
