Here's why:

* Placenta: This organ develops in the uterus during pregnancy. It acts as a bridge between the mother and the developing fetus.

* Food Delivery: The placenta receives nutrients and oxygen from the mother's blood and transfers them to the embryo/fetus through the umbilical cord.

* Waste Removal: The placenta also carries waste products from the embryo/fetus back to the mother's blood to be filtered out.
