1. Lesson 3: Human
Reproductive System
Foundation Science SC 22101

2. Functions of the
Reproductive System
Male – to produce sperm and deliver it to
female reproductive system.
Female – produces eggs and provides a place
for an embryo to develop.

3. Externally Visible
Reproductive Organs
Penis – male organ that delivers semen to the
female reproductive system.
Vagina – female organ that receives sperm
from the male, also provides a path for
baby from uterus to outside world.

4. Sperm
Sperm have 23
chromosomes
Sperm is made by
the testes
The job of sperm is
to fertilize the
egg…….

5. What does a Sperm Cell Live for?
Egg
To fertilize a
female egg

6. Egg
Egg has 23 chromosomes also.
Eggs are produced by the
ovaries.

7. Functions of Female
Reproductive Organs
Ovaries make
eggs
Uterus is where
fetus grows
into a baby
Fallopian tube is
where sperm
fertilize egg

8. Functions of Female
Reproductive Organs
Ovaries make
eggs
Uterus is where
fetus grows
into a baby
Fallopian tube is
where sperm
fertilize egg

9. Developmental Steps: Zygote  Embryo  Fetus
1) Egg is made in the
ovary
2) Egg released from
ovary and enters
fallopian tube
3) Sperm fertilizes egg
creating a 46
chromosome zygote
4) Zygote replicates and
becomes an embryo
5) Embryo embeds into
uterus to become a
fetus

Label Female
Reproductive
Organs:
ovaries, vagin

an tubes, and
uterus
Questions
2) In the uterus there is an endometrium
and a myometrium. “Metrium”
means “womb” or “uterus”. DON’T
look it up, but guess what an
endometrium is.
3) What does “myo” mean in Latin (ask
me for help)? Can you now guess
what a myometrium is?
