* Uterus: This is a muscular organ in the female reproductive system. It provides a safe and nurturing environment for the developing embryo, providing:
* Protection: The uterus is a muscular sac that protects the embryo from external forces.
* Nutrition: The placenta, which forms from the embryo's tissues and the uterine lining, provides oxygen and nutrients to the developing embryo.
* Waste Removal: The placenta also removes waste products from the embryo.
