3. Female Reproductive
System
1
How are girls and boys different?
Girls have sex organs called ovaries
2
Vocabulary:
ovaries
The female sex organ that holds the
eggs
3
Ovaries produced hormones that make
a girl’s body grow
in different ways than a boy’s body
4
The two ovaries also store the cells that
develop into babies
These cells are called egg cells
5
Vocabulary:
Egg cells
The female reproductive cells stored
in the ovaries
6
Females are born with all their eggs
inside them
Then when a girl gets old enough, one
egg leaves one ovary every month
7
But where does the egg go?
It passes from the ovary into a tube
called the fallopian tube
8
It takes about 3 days for the egg to
travel down this tube
to an organ called the uterus
9
Vocabulary:
uterus
An organ in the female body where a
baby can grow and develop
10
By this time, tissues lining the uterus
have filled with blood
They are ready to hold a developing
baby
11
If the egg cell is fertilized, it will stay
in the uterus
It will develop into a fetus and grow
into a baby
12
Vocabulary:
fetus
A fertilized egg that grows into a baby
13
If the egg cell is not fertilized,
the egg and the blood from the lining of
the uterus are not needed
14
They leave the uterus and flow out of
the body through the vagina
Vocabulary:
vagina
A passageway that leads out of a
female’s body
15
The vagina is also called the birth canal
because a baby passes through it when
being born
16
Vocabulary:
Birth canal
The tube a baby passes through when it
is born (vagina)
17
It takes about 5 days for the blood to
flow out of the female’s body
The female is having a period
18
Vocabulary:
period
The time when blood from the uterus
flows out of the female’s body
19
The blood flow is part of the menstrual
cycle
Vocabulary:
Menstrual cycle
The cycle in the female’s body
beginning with the release of the egg
cell and ending with the period
20
Things that happen again and again in
the same order form a cycle
The menstrual cycle takes place about
once a month from puberty to
menopause
21
Having a period is part of what makes
girls and boys different
It is one of the changes in a girl’s body
that happens during puberty
