* Uterus: This is a muscular organ that houses the developing fetus throughout pregnancy. The uterus is lined with a specialized tissue called the endometrium, which provides nourishment and support to the growing embryo.
* Placenta: A vital organ that develops from the embryo's tissues and the mother's endometrium. The placenta acts as a barrier between the fetal and maternal bloodstreams, allowing for the exchange of nutrients, oxygen, and waste products.
* Umbilical cord: Connects the fetus to the placenta. It carries the umbilical vein, which carries oxygenated blood and nutrients to the fetus, and the umbilical arteries, which carry deoxygenated blood and waste products back to the placenta.
Therefore, the structure of the mother where the fetal pig develops is the uterus, facilitated by the placenta and connected through the umbilical cord.
