A, B and C
The placenta is an organ that connects the developing foetus to the wall of the uterus to allow nutrient uptake, waste elimination, thermoregulation and gas exchange via the mother's blood supply. The placenta provides oxygen and nutrients to growing foetus and removes waste products from the fetus's blood. The placenta attaches to the wall of the uterus, and the foetus's umbilical cord develops from the placenta.
