Which hollow female reproductive organ houses a fertilized egg and supports its development?

• A. Cervix
• B. Vas Deferens
• C. Uterus
• D. Testes

Answer: (C)

The uterus is the hollow organ in which a fertilized egg implants and develops into a fetus. Its inner lining, the endometrium, thickens each cycle to ready for implantation, and once the embryo implants there, it grows and is nourished by maternal blood via the placenta. The uterus provides the space, protection, and environment necessary for fetal development and eventual birth through its muscular contractions. The cervix connects the uterus to the vagina but is not where development occurs; the other two structures are male reproductive organs, so they do not house a developing embryo.
