All of the options listed describe functions that are related to the placenta, but primarily, the placenta is known for **nourishing the embryo**. It facilitates the transfer of nutrients and oxygen from the mother to the developing fetus and removes waste products from the fetal blood.
- **It protects the embryo**: While the placenta does provide some level of protection, this is more about immunological functions and barrier properties rather than direct physical protection.
- **It helps keep the embryo’s temperature constant**: This is not a primary function of the placenta.
- **It cushions the embryo from shock**: This is mainly the role of the amniotic fluid and the surrounding tissues, although the placenta helps in creating a stable environment.
So, while the placenta contributes to aspects of protection and stability, its primary and most direct function from the options provided is that it **nourishes the embryo**.
