What is the function of the cervix?

Site of implantation; and where an embryo develops.
What is the function of the Oviduct?
Site of fertilisation.
What is the function of the ovary?
Produces and stores ova/eggs.

What is each ovum surrounded by and what does this do?
Surrounded by a follicle that protects the developing embryo.
What is a fertilised egg/ova known as?
A Zygote.
What hormones does the Ovaries release?
Progesterone and oestrogen.
What is a corpus luteum?
