- Production of female gamete or egg.
Oviduct:
- Transfer of female gamete from the ovary.
- Site of fertilisation.
Uterus:

The embryo inside the mother’s body gets nourishment through the placenta.
Placenta is a special disc like tissue embedded in the mother’s uterine wall and connected to the embryo. Placenta provides a large surface area for glucose and oxygen, and nutrients to pass from the mother’s blood to the embryo.
