5. Male Reproductive System
Structure Function
Testicles (Testis) Produces
Testosterone &
Sperm
Scrotum Contains the
testicles & regulates
temperature
Urethra Tube that carries
both urine and
semen out of the
penis.

6. Male Reproductive System
Structure Function
Vas Deferens Transports mature sperm
to the urethra for
ejaculation.
Prostate Walnut-sized structure
that adds additional fluid
to the ejaculate &
nourishes sperm
Seminal
Vesicle
Produces a sugar-rich
fluid (fructose) that
provides sperm with a
source of energy to help

7. Male Sex Hormone
● Testosterone
● Produced in the testicles
● Affects a male’s appearance
and sexual development
● Stimulates sperm
production/sex drive
● Helps build muscle and bone
mass

8. Go the classwork section
and complete the
Actively assignment:
Male Reproductive
Structures

9. Female Reproductive System
Structure Function
Vagina Birth canal
Cervix The lower part of
the uterus that
dilates during
childbirth
Uterus Home for a
developing fetus
(baby)

10. Female Reproductive System
Structure Function
Ovary Produces eggs and
female sex
hormones (estrogen
& progesterone)
Fallopian Tube Connected to
ovaries and uterus -
travel channel for an
egg

11. Female Sex Hormones
● Estrogen
○ Created in the ovaries
○ Responsible for female sexual
development - breasts, wider
hips, etc.
○ Regulates the menstrual cycle

● Growth and repair in the

19. What is
Differentiation?
● *This is a KEY TERM -
KNOW THIS ONE!!!*
● The process of
development during
which embryonic cells
specialize and diverse

20. What is
Differentiation?
● Animals are made up of many
different cell types, each with
specific functions in the body
● The differentiation of cells
during embryogenesis is the
key to cell, tissue, organ, and
organism identity

21. Storyline Mascot -
Cheetah Differentiation
When cells
use different
parts of the
DNA
sequence to
perform
different
functions.

22. What is
Differentiation?
● All cells have the SAME DNA.
● Different parts of the DNA are
used for instructions
depending on the cell type
○ Ex.) Heart cells would use
different parts of the DNA
sequence as opposed to
