Name the structures labeled C and D in the female reproductive system and describe their functions.

C) Oviduct/Fallopian Tube:
This tube connects the ovary to the uterus. It is the primary site where fertilization of an egg by sperm typically occurs. The oviduct also transports the fertilized egg (zygote) or unfertilized egg towards the uterus using cilia and muscular contractions.

D) Vagina:
The vagina is a muscular, elastic canal that connects the uterus to the outside of the body. It serves as the birth canal during childbirth, receives the penis during sexual intercourse, and is the exit route for menstrual flow.
