Structure Function
Ovary They produce oocytes for ertilization and
they produce the reproductive
hormones, oestrogen and progesterone.
Fallopian tube (oviduct) These are narrow tubes that are attached
to the upper part of the uterus and serve
as pathways for the ova to travel from
the ovaries to the uterus. Fertilisation of
an egg by a sperm normally occurs in the
fallopian tubes.
Uterus Site where the blastocyst implants.
Allows for the development and growth
of the fetus. Contracts during birth to aid
the expulsion of the fetus.
Uterine horn The uterine horns support sperm
transportation to the oviducts and are
the site for fetal growth and
development during pregnancy.
Fimbriae Its main function is to collect the egg
released from the ovary after ovulation
and draw it into the fallopian tube.
Endometrium The endometrium is the inner lining of
the uterus. Each month, the
endometrium thickens and renews itself,

preparing for pregnancy. If pregnancy
doesn’t occur, the endometrium sheds in
a process known as menstruation. If
conception takes place, the embryo
implants into the endometrium.
Cervix Anatomically, it must allow sperm
passage into the uterus through the
endocervical canal, and it must produce
mucus to facilitate sperm entry. The
cervix helps keep the baby in place until
it’s fully developed.
Vagina It’s the pathway (the birth canal) through
which a baby leaves a woman’s body
during childbirth. It’s the route through
which menstrual blood leaves the body
during periods.
Labia Enclose and protect the other external
reproductive organs.

Structure Function
Epididymis Functions to mature and store sperm
cells (at least 20 days). Sperm
become motile during their stay in
the epididymis. Expels sperm with
the contraction of muscles in the
epididymis walls to the vas deferens.
Seminal vesicle The two seminal vesicles are glands
that produce the fluids that will turn
into semen. The muscular tissue
